Defense Travel System

The Defense Travel System (DTS) is a fully integrated, , end-to-end travel management system developed and operated by the () to automate the authorization, booking, documentation, and reimbursement processes for official temporary duty (TDY) and local travel by , employees, and certain contractors. Accessible via a secure , DTS enables 24/7 real-time reservations for , lodging, and rental cars through integration with a designated Travel Management (TMC), while incorporating pre-audit compliance checks against the Joint Travel Regulations (JTR) to ensure regulatory adherence. The system supports various user roles, including travelers who create trip authorizations and vouchers, Defense Travel Administrators (DTAs) who manage site access and permissions, and Authorizing Officials (AOs) who approve documents, with all transaction data retained for up to 10 years for auditing and financial management purposes. Initiated in response to inefficiencies identified in the 1993 National Performance Review, the development of DTS began with the establishment of a to Reengineer Travel in June 1994, culminating in a report issued in January 1995 that recommended a paperless, automated to streamline travel operations. The DTS Program Management Office (PMO) was created on December 13, 1995, under the oversight of the Under Secretary of Defense (Comptroller) and the Under Secretary for Acquisition, Technology, and Logistics, with the system designated as a major automated on May 28, 2002, and approved for full production and deployment in October 2003 at an estimated lifecycle cost of $2.24 billion. Mandated as the 's single standard travel system in July 2001, DTS achieved full implementation across all sites by fiscal year 2006, as directed by the Deputy Secretary of Defense in October 2004, and has since been managed by the Defense Travel Management Office (DTMO), established in February 2006, in coordination with the (DFAS) for payment processing. As of fiscal year 2025, DTS remains the primary platform for travel, handling approximately $10 billion in annual expenditures, following a temporary shift to the MyTravel system during reduced travel periods influenced by the ; a directive issued on May 24, 2023, repealed the mandatory use of MyTravel, requiring all new travel authorizations to revert to DTS effective July 13, 2023, and fully phasing out MyTravel by September 2023. Key benefits include enhanced efficiency through electronic workflows that reduce processing times, improved compliance via automated JTR validation, and greater auditability for financial oversight, serving over 3 million personnel across components. The system also integrates with the Government Travel Charge Card (GTCC) program, mandating its use for all official travel expenses to minimize out-of-pocket costs for travelers.

Overview

Purpose and Functionality

The Defense Travel System (DTS) is a fully integrated, electronic, end-to-end travel management system designed to automate Temporary Duty (TDY) and local travel processes for the (DoD). It serves as the primary platform for DoD personnel to handle official travel, covering all aspects from planning to reimbursement while ensuring adherence to the Joint Travel Regulations (JTR). By centralizing these operations, DTS eliminates much of the manual paperwork associated with traditional travel management. At its core, DTS enables users to create travel authorizations, book commercial reservations for flights, hotels, and rental cars in real time, estimate trip costs, request cash advances, submit post-travel expense vouchers, and process reimbursements through or the Government Travel Charge Card (GTCC). The system incorporates built-in tools for rate lookups and comparisons to promote cost-effective decisions, such as selecting the lowest logical airfare or preferred lodging options. Additionally, it automates direct payments to vendors and retains electronic documents for up to 10 years, providing 24/7 accessibility for audits and reviews. DTS delivers key benefits by enforcing JTR compliance through automated pre-audit flags and reason codes, which flag potential policy violations and reduce improper payments. This automation significantly lowers administrative burdens on components, streamlining workflows and enhancing overall efficiency in travel management. On a broader scale, the system processed an average of $6.1 billion in annual travel expenditures as of fiscal years 2016-2018 and supports over 1 million registered users across more than 9,500 sites worldwide as of 2025.

Scope and Usage

The Defense Travel System (DTS) is accessible to a range of eligible users within the Department of Defense (DoD), including active duty and reserve component service members from all military branches such as the Army, Navy, Air Force, Marine Corps, Space Force, and Coast Guard when operating under DoD authority, as well as DoD civilian employees. Dependents of service members or civilians may use DTS for specific purposes like renewal agreement travel or in-place consecutive overseas tours leave, while invitational travelers—non-DoD personnel invited for official events—can access it with assistance from a designated travel administrator. Additionally, DoD personal services contract employees are eligible for temporary duty (TDY) travel when sponsored under specific contracts, though most non-personal services contractors and nonappropriated fund employees are prohibited from direct access. DTS manages various types of official travel, primarily TDY for duties away from the permanent duty station, which may incorporate certain relocation elements but does not fully support (PCS) moves. It also covers local travel for expenses like conference attendance or mileage within the vicinity of the duty station, group travel for coordinated official movements, and invitational travel for authorized non-DoD participants. Personal or non-official trips are explicitly excluded, ensuring DTS remains focused on government-funded, mission-related activities in compliance with the Joint Travel Regulations. Organizationally, DTS is mandatory for most DoD travelers across all components and agencies for supported travel functions, as established by DoD policy since its full operational capability. Usage has scaled significantly, with DoD travel obligations processed through DTS reaching approximately $8.5 billion in fiscal year 2006 and averaging $6.1 billion in annual payments from fiscal years 2016 to 2018, reflecting growth in transaction volume and integration with financial systems like the Defense Enterprise Accounting and Management System (DEAMS) for obligations and reimbursements. As of fiscal year 2025, the system is part of a Defense Travel Enterprise handling approximately $10 billion in annual expenditures. Key limitations define DTS's boundaries: it is restricted to DoD personnel and does not extend to non-DoD federal agencies, requiring a (CAC) with a valid DoD certificate for secure access and authentication. The system handles only commercial transportation, lodging, and rental arrangements, excluding government-provided options like , to align with travel policies favoring commercial modes for efficiency.

History and Development

Inception and Early Planning

The Defense Travel System (DTS) was envisioned in the mid-1990s as part of the Department of Defense's () broader initiatives aimed at modernizing outdated, paper-based travel management processes across military services and defense agencies. In 1995, initiated efforts to develop a standardized, automated system to replace fragmented legacy travel operations, which relied heavily on manual workflows and disparate commercial travel offices. This conceptual development stemmed from the National Performance Review's call for travel system reengineering in 1993, but gained formal momentum through the 1995 Travel Reengineering Report, which highlighted systemic inefficiencies in temporary duty travel (TDY) handling. Key drivers for DTS's inception included the need to drastically reduce travel processing times from weeks to mere days, lower administrative costs associated with manual reimbursements and reservations, and enhance auditability to better track expenditures amid a rapidly expanding travel budget. By the late 1990s, 's annual travel spending had reached approximately $5.3 billion, underscoring the urgency for a more efficient, centralized approach to manage the growing volume of official trips for over 3 million personnel. The 1995 Travel Reengineering Report identified rigid, compliance-focused policies and outdated practices as major bottlenecks, recommending to streamline end-to-end travel workflows and reduce error-prone paper documentation. Initial planning for DTS was led by predecessors to the Defense Travel Management Office (DTMO), notably the Program Management Office–Defense Travel System (PMO-DTS), established in December 1995 by memoranda from the Under Secretary of Defense for Acquisition and Technology and the Under Secretary of Defense (Comptroller)/. Economic analyses during this phase adhered to guidelines in OMB Circular A-94 for benefit-cost evaluations, ensuring the proposed system would deliver measurable returns on investment through reduced operational overhead. DTS was designed from the outset as a web-based platform to enable electronic authorizations, bookings, and reimbursements, with plans for integration into emerging (ERP) tools to facilitate seamless data sharing with financial systems. Early milestones included concept approval and the award of the initial development contract in May 1998 to TRW Inc. (later acquired by Northrop Grumman), valued at $263.7 million over five years, marking the transition from planning to procurement. By 1999, the focus had solidified on automating the full end-to-end workflow—from trip authorization and reservations to expense vouchers and reimbursements—to eliminate redundancies in legacy processes. This foundational planning paved the way for pilot testing beginning in 2001.

Rollout and Expansion

The Defense Travel System (DTS) was initially deployed as a pilot program in June 2001 at 27 sites across the (DoD), where it tested core functionalities including travel authorizations and expense vouchers to streamline temporary duty travel processes. This phase focused on validating the system's end-to-end capabilities in a controlled environment, enabling early users to create electronic travel documents and integrate with existing DoD networks. Expansion accelerated in the following years, with DTS reaching 77 operational sites by October , followed by an additional 90 sites by October 2006. By late 2006, the system provided full access at over 8,700 sites worldwide, supporting hundreds of thousands of personnel in managing their needs. Key to this scaling were integrations with Global Distribution Systems (GDS) such as and , which facilitated real-time bookings for commercial air, hotel, and rental car reservations directly within the platform. Additionally, its web-based architecture allowed secure access via 's non-classified router network, promoting widespread adoption without requiring specialized hardware. By 2007, DTS had processed $2.4 billion in travel expenses, representing a significant portion of the DoD's $9 billion annual travel budget and demonstrating its growing centrality to departmental operations. Mandatory use was enforced across all services by the mid-2000s, with the Corps, for instance, requiring full implementation at eligible sites starting in 2005 to replace legacy paper-based systems. This enforcement ensured standardized management, reducing administrative overhead and enhancing compliance with Joint Travel Regulations.

Challenges and Reforms

The implementation of the Defense Travel System (DTS) encountered significant early challenges, as detailed in a 2006 () report. Training gaps were prominent, with inadequate reviews by authorizing officials resulting in 18% of travel vouchers being paid without reasonable assurance of accuracy and 29% lacking required receipts. System glitches, stemming from insufficient testing, led to inaccurate displays of flight options and airfares, persisting even after the August software release. Low adoption rates exacerbated these issues; for instance, underutilization at deployed locations prompted the to incur an additional $5.6 million in costs for manual processing of 177,000 vouchers compared to 84,000 electronic ones between October 2004 and February 2005. Furthermore, DTS's inability to track unused tickets contributed to delayed reimbursements, with the reporting $14 million in untracked unused tickets in the third quarter of 2005. Criticisms of DTS centered on user interface difficulties, integration bugs with financial systems, and operational bottlenecks. Service members frequently described the system as "unfriendly" due to its complex navigation, such as requiring users to navigate through four or five screens to view flight details adequately, which hindered efficient use. Integration challenges included the need for 18 additional interfaces with legacy financial systems, estimated to cost over $30 million with uncertain funding, leading to persistent errors in data transfer and compliance with regulations like the Fly America Act. Over-reliance on approvers for authorizations and reimbursements created bottlenecks, slowing processing times and increasing administrative burdens, as noted in GAO assessments of the system's design flaws. By 2007, overall usage remained low at approximately 27% of the Department of Defense's $9 billion travel budget, processed through DTS at $2.4 billion, reflecting these usability and integration shortcomings. Reform efforts gained momentum in the late to address these systemic issues. In June 2017, the Department of Defense established the for Travel (CFT-T) to review existing travel policies, evaluate technical solutions, and recommend enhancements for a more modernized capability. This initiative led to the August 2018 award of a $9.3 million contract to for developing a system intended as a DTS replacement, with prototype development advancing into 2019 to improve and integration. Additionally, multiple DoD Travel Alerts (DTAs) were issued throughout the to enforce compliance with travel regulations, mitigate improper payments, and guide users on policy updates amid ongoing system limitations. These reforms yielded gradual improvements in DTS adoption and functionality, transitioning to near-mandatory use across the Department of Defense by the late 2010s, with electronic voucher processing reaching about 73% for the in 2008 alone. GAO oversight persisted, noting that by 2009, the Department had satisfactorily addressed 6 of 14 prior recommendations, including better management of unused tickets and restricted airfares, though challenges like comprehensive utilization metrics remained unresolved. Overall, these efforts reduced manual processing costs—electronic vouchers costing $2.47 versus $36.52 for manual ones—but did not fully eliminate persistent hurdles.

System Components

Authorizations and Reservations

The authorizations and reservations phase in the Defense Travel System (DTS) represents the pre-travel planning stage, where Department of Defense (DoD) personnel create and secure approval for temporary duty (TDY) travel orders. This process ensures compliance with the Joint Travel Regulations (JTR) and optimizes costs through automated tools. Travelers initiate an authorization by logging into DTS and selecting "Create New Document" followed by "Routine TDY Trip," entering essential details such as mission purpose, TDY locations, departure and return dates, and estimated itinerary including modes of transportation like commercial air, rail, or rental vehicles. The system restricts trip durations to no more than one year and limits authorization creation to within six months of the travel start date to maintain fiscal accuracy. During authorization creation, travelers input mission-specific information, including estimated itineraries and entitlements, with DTS automatically calculating costs based on current JTR rates for lodging, meals, and incidental expenses (M&IE). The system populates amounts according to the TDY location and itinerary, adjusting for factors like duty conditions or provided meals, while requiring secure flight passenger data (e.g., name, date of birth, Known Traveler Number) for bookings. Travelers must also specify needs such as rental cars, which are limited to approved vendors. This auto-calculation feature promotes efficiency and adherence to standardized rates, reducing manual errors in cost projections. Reservation booking occurs directly within DTS through integration with Travel Management Companies (TMCs) and Global Distribution Systems (GDS) such as , enabling seamless searches and bookings for commercial flights, , and rental cars. The system enforces the use of the Commercial Air Program's City Pair fares, which are mandatory for all official commercial air travel when available; commercial air is generally required for TDY over 400 miles one-way unless exceptions apply, by prioritizing the lowest-cost compliant options that comply with the Fly America Act and U.S. requirements. reservations follow the Invitational Travel Lodging Program (ILTP) or commercial standards, with DTS suggesting options based on the TDY site and auto-applying limits; rail bookings require TMC coordination. Tickets are issued post-approval by the TMC, with automatic cancellation if authorization is not signed within 72 hours of departure. The approval workflow involves completing DTS modules for reservations, expenses, and , followed by signing and to the (AO) or organizational representatives via an chain. AOs review for , including justifications for any deviations; travelers should submit authorizations allowing 2-3 weeks for CONUS travel and 45-60 days for OCONUS travel to facilitate timely ticketing. Travelers can request advances in the module, up to 80% of estimated costs standardly or 100% if justified by financial need, using a valid Line of Accounting (LOA); these funds are disbursed via the Government's (GTCC) or . Key concepts in this phase include constructed travel comparisons, which justify deviations from optimal routes, such as using a for distances exceeding 400 miles one-way or 800 miles round-trip; travelers must submit a Constructed Travel Worksheet (CTW) via DTS's Other Authorizations and Pre-Audit module for AO evaluation against JTR criteria, preferring when feasible. DTS use is mandatory for all official TDY travel except in emergencies, ensuring standardized processes and cost controls across the department. Profile details, such as GTCC information, personalize these authorizations but are managed separately.

Vouchers and Reimbursements

In the Defense Travel System (DTS), travelers create vouchers to document and claim for actual expenses incurred during official temporary duty (TDY) travel, using the previously approved as a for reconciliation. Upon return, travelers access DTS to generate a from the authorization, updating the itinerary with actual dates and locations, entering precise expenses such as , transportation, and other allowable costs via predefined categories (as of August 19, 2025, the “Create Your Own Expense” field was replaced with new expense categories to reduce unauthorized claims), and uploading digital receipts for any item exceeding $75 or as required by policy. The system automatically reconciles these actuals against the authorization's estimated costs, flagging deviations like excess or unapproved itinerary changes for justification; travelers must complete and submit the voucher within five working days of return to comply with policy, ensuring timely processing and avoiding delinquency notifications. DTS automates reimbursement calculations by applying current rates, mileage allowances, and actual substantiated costs, with payments split between the traveler's personal account for out-of-pocket expenses and direct to the Government Travel Charge Card (GTCC) vendor for charged items. For 2025, the standard Continental (CONUS) meals and incidental expenses (M&IE) rate is $68 per day, though tiered non-standard areas range up to $92; the system prorates for partial days (e.g., 75% on the first and last days), computes mileage at the authorized rate (e.g., $0.70 per mile for in 2025), and adjusts for any actual receipts provided, generating a financial summary for review before finalization. Profile-based preferences, such as default payment methods, may influence how disbursements are allocated but do not alter core calculations. The voucher undergoes an automated audit process in DTS, which performs built-in compliance checks against the Joint Travel Regulations (JTR), identifying potential violations such as excessive claims or missing justifications, before routing to the approving official for manual review and . Approvers verify adherence to mission requirements and JTR directives, resolving any flags; once approved, reimbursements are processed via (EFT), with funds typically disbursed to the traveler and GTCC vendor within 3-5 business days if no errors are present. This streamlined workflow minimizes payment delays while enforcing fiscal accountability. For trips involving non-preferred modes of transportation, DTS handles special cases through Constructed Travel Worksheets (CTWs), which compare the actual costs chosen by the traveler against the government-preferred constructed itinerary to determine allowable reimbursements. As of the April 9, 2025, system update, DTS automatically prompts for CTW attachment when required—such as for one-way personally owned vehicle () trips exceeding 400 miles or round trips over 800 miles—and integrates the worksheet's cost comparison directly into the voucher review, allowing approvers to assess and limit reimbursements accordingly without manual overrides. This enhancement aligns DTS with recent JTR revisions, simplifying compliance for surface travel while preserving cost controls.

Profiles and Groups

In the Defense Travel System (DTS), profiles serve as the foundational data structures that store personal, organizational, and information essential for system functionality. There are two primary types of personal profiles: profiles, which provide basic identity and details for non-travelers such as administrators, and / profiles, which extend these with comprehensive and payment data for individuals performing official business. / profiles include user-specific elements such as personal details like , , and payment preferences, as well as duty station information encompassing addresses, time zones, and distances to airports for calculations. Common profiles, often tied to organizations, incorporate shared data like lists that direct workflows across multiple users. Organization representatives, known as Defense Travel Administrators (DTAs), handle the management of profiles by creating and updating organizational hierarchies, assigning permissions, and overseeing sub-organizations to ensure proper data segregation. DTAs assign profiles to specific organizations, automatically linking them to default routing lists and permission levels, such as Level 0 for basic access upon approval. They also facilitate reassignments by detaching profiles from one organization and transferring them to another, which requires coordination to maintain and prevent duplicate Social Security Numbers across entities. For personnel with multiple roles, such as Reserve Component members, DTAs can create up to two user/traveler profiles, each residing in distinct organizations and identified with SSN suffixes like "R" for reserves, to support segregated access and . Groups in DTS function as virtual containers that safeguard personally identifiable information (PII) by restricting document access in accordance with the Privacy Act, enabling secure handling for multi-traveler scenarios. Each traveler is assigned to a primary group affiliated with their organization, managed by the Lead DTA, while secondary groups can be established for targeted access needs, such as component-level oversight or support. Group planners, typically involving Lead DTAs and component representatives, coordinate the creation of these groups, defining ownership, naming conventions, membership criteria, and access protocols to facilitate collaborative missions. For multi-traveler missions, group planners add members either manually, one at a time, or automatically through Global Group Membership Rules (GGMRs) that dynamically include or exclude personnel based on predefined criteria, allowing shared visibility of itineraries and consolidated authorizations within the group. Maintenance of profiles and groups emphasizes accuracy to support reliable reimbursements and system integrity. New users can self-register via the DTS Self-Registration Tool, after which DTAs review and approve the , granting initial and . Travelers are responsible for verifying and updating their through the My feature in the DTS , including personal details and travel preferences, while DTAs handle restricted fields like rank or changes and issue notifications for PII updates. For groups, DTAs perform ongoing tasks such as adding or removing members, editing GGMRs, and generating reports to ensure membership reflects current organizational needs and prevents errors. Regular reviews by DTAs and users help maintain data currency, with features like resets available to resolve issues such as CAC changes or detached .

User Roles and Access

Traveler Responsibilities

Travelers in the Defense Travel System (DTS) are responsible for maintaining an accurate and up-to-date personal profile, including organizational details, financial information, and Government Travel Charge Card (GTCC) data, to ensure proper processing of travel documents. This includes verifying contact information and preferences before initiating any travel requests. Core duties encompass creating and digitally signing authorizations prior to travel, detailing the trip's purpose, itinerary, estimated expenses, and applicable allowances in compliance with the Joint Travel Regulations (JTR). Upon return, travelers must submit vouchers within five working days, adjusting for actual expenses and attaching required receipts for all expenditures of $75 or more, as well as lodging receipts unless using flat-rate per diem. Additionally, travelers are obligated to respond promptly to any audit queries from the Defense Travel Management Office (DTMO) or financial managers, as failure to do so may result in personal liability for erroneous claims under federal statutes such as 18 U.S.C. § 287 and 31 U.S.C. § 3729. Best practices for travelers include using DTS exclusively for all official bookings to guarantee compliance and optimal rates, such as through the GSA City Pair Program for air travel. Prior to travel, individuals should review current per diem rates on the DTMO website to anticipate reimbursable amounts for lodging, meals, and incidentals. Any deviations from the authorized itinerary, such as changes in transportation mode or unusual expenses, must be reported immediately and justified in the voucher, with prior approval sought where required under JTR limits prohibiting luxury accommodations or premium-class travel without exception. Travelers should also ensure their GTCC account remains in good standing to facilitate split disbursements, where a portion of reimbursement is directed to the card issuer for official charges. For mobile access, the CWTSato To Go app allows travelers to create authorizations, book reservations, and manage itineraries on the go, mirroring desktop functionality. Compliance requirements emphasize adherence to JTR guidelines, including using the most economical travel options and avoiding personal expenses on the GTCC during official trips. Travelers must exercise fiscal responsibility equivalent to handling personal funds, ensuring all inputs in DTS are valid and accurate to prevent overpayments or delays. Common pitfalls include overlooking constructed travel rules, where opting for an alternate mode requires and proof of savings; failure to do so can result in travelers bearing out-of-pocket costs beyond the authorized amount. Late submissions or missing receipts often lead to failures and delays, while inaccurate adjustments for unofficial days like leave can trigger overpayment recoveries. To mitigate these, travelers should monitor document status in DTS and utilize available worksheets for pre- and post- planning from the DTMO.

Approver and Administrative Roles

In the Defense Travel System (DTS), approver roles are essential for overseeing travel documents to ensure adherence to Department of Defense policies and regulations. Authorizing Officials (AOs), often referred to as trip authorizers, hold the authority to review, edit, and approve both authorizations and vouchers, verifying mission necessity, funding availability, and compliance with the . These officials bear pecuniary liability for any erroneous approvals, making their role critical in preventing improper use of government funds. A more limited approver role is the Non-DTS Entry Agent (NDEA), previously known as Non-DTS Entry (NDE), who performs basic sign-off functions by inputting and digitally signing vouchers on behalf of travelers without direct DTS access, using supporting forms like . NDEAs cannot approve authorizations or edit documents extensively but must attach required documentation, such as receipts for expenses exceeding $75. Administrative roles in DTS focus on system management and user oversight, distinct from direct approval duties. Organization Defense Travel Administrators (ODTAs) are responsible for assigning permissions, maintaining user profiles, and managing access within their organization to ensure proper . They handle tasks such as updating routing lists and assisting with user in-processing, which supports efficient document flow without involving travel execution. Travel Management Coordinators complement these efforts by enforcing local policy interpretations, such as organization-specific travel restrictions or budgeting guidelines, to align DTS usage with unit-level requirements. DTS employs a permission with levels ranging from 0 to 9 to control access and functionality based on role needs. Level 0 provides basic access for all users, including viewing and creating personal documents. Level 1 allows view-only access to certain administrative tools. Level 2 enables access to trips awaiting action, required for Authorizing Officials. Levels 3-6 support various administrative functions, such as (Level 3), (Level 4), (Level 5), and lines of accounting (Level 6). Higher levels (7-9) are reserved for component and DoD-level oversight. This structure allows for reassignment of documents across users and provides access to track changes, ensuring accountability throughout the process. Permissions are assigned exclusively by DTAs using tools like the DTA Maintenance module, preventing overlap that could compromise . Collectively, these roles uphold key responsibilities centered on fiscal law compliance, such as the , by scrutinizing expenditures against appropriated funds and JTR guidelines. Approvers and administrators monitor usage metrics through DTS reports, including document processing times and error rates, to identify trends in non-compliance. They also resolve escalated errors, such as rejected payments or account discrepancies, by coordinating with finance teams or elevating issues to the , minimizing disruptions to travel operations.

Integration and Technology

Technical Architecture

The Defense Travel System (DTS) is a web-based application hosted on secure Department of Defense (DoD) servers, utilizing a client-server model that enables access via standard web browsers such as Google Chrome and Microsoft Edge. This architecture facilitates data exchange primarily through XML formats, supporting seamless processing of travel authorizations and reimbursements within the system. Security is integral to DTS's design, incorporating (CAC) authentication for user verification and (RBAC) to enforce permissions based on user roles. Sensitive data, including (CUI) and Privacy (PRVCY) records, is protected through in transit and at rest, with additional measures like data masking on backup tapes. The system complies with cybersecurity standards, including elements of the 8500 series, ensuring alignment with broader requirements. DTS demonstrates through dual-site configurations that enable concurrent , accommodating peak loads from thousands of simultaneous users across components. Periodic maintenance windows are scheduled to support upgrades and ensure system reliability, such as the downtime planned for November 21, 2025, from 2100 to 0200 on November 22. Originally developed on legacy technologies and first deployed in August 2001 at , DTS has evolved to incorporate modern web standards, including mobile compatibility on government-issued devices by the mid-2010s and beyond.

External Integrations

The Defense Travel System (DTS) integrates with the Defense Enterprise and (DEAMS) to facilitate fund and for travel expenses, enabling real-time financial data compilation for auditing and compliance purposes. This interface supports the processing of travel by exchanging data on authorizations and reimbursements, helping to address delays in payments for Department of Defense personnel. Additionally, DTS connects with the (DFAS) through (EFT) for disbursing reimbursements directly to travelers' bank accounts and settling Government obligations upon voucher approval. For travel bookings, DTS links with global distribution systems (GDS) such as and to provide real-time availability and reservations for hotels and rental cars, ensuring access to preferred commercial lodging options. rates for lodging, meals, and incidental expenses are sourced from the Defense Travel Management Office (DTMO) repository, with DTS automatically applying these rates—including 75% reductions for first and last travel days—based on locality-specific bulletins published in the . DTS interfaces with other Department of Defense systems, including the (DEERS), to validate traveler profiles and personnel data for accurate authorization and access control. It also connects with logistics tools, such as those under the Defense Personal Property Program, to support (PCS) moves by incorporating transportation entitlements and household goods shipment details into travel documents. Data exchange between DTS and these external systems occurs via secure application programming interfaces () for real-time interactions and batch file transfers for bulk processing, such as voucher submissions to DFAS. These mechanisms maintain comprehensive audit trails to ensure compliance with the Joint Travel Regulations (JTR), the DoD adaptation of the Federal Travel Regulation (FTR), through tools like the Travel Policy Compliance Tool that flags potential violations during voucher review.

Training and Support

Available Resources

The Defense Travel System (DTS) provides users with a comprehensive suite of official training modules accessible through the TraX portal, managed by the Defense Travel Management Office (DTMO). TraX offers web-based training (WBT) courses covering key functionalities, including authorizations, vouchers, and user roles, designed to build foundational skills for effective system use. For instance, the DTS 101 course introduces basics on creating travel documents such as authorizations, vouchers, and local vouchers, and is recommended for all new users. Upon completion, participants receive digital certificates that verify proficiency and are often required for obtaining system permissions. Official guides and manuals further support user education, with the Defense Travel Administrator (DTA) Manual providing detailed chapters on topics like system access, organization setup, and group management. The DTS Best Practices Guide, last updated in July 2025, offers practical direction for developing local business rules and optimizing DTS processes across organizations. Self-help tools within DTS and related portals include interactive dashboards for real-time navigation, comprehensive FAQs searchable via TraX, and video tutorials demonstrating common tasks like expense entry. Integrated features such as constructed travel worksheets and calculators assist users in pre-trip planning and reimbursement calculations directly in the system. All these resources are freely available to authorized DoD personnel through the secure portal, with initial training mandatory for new roles and annual refreshers encouraged to maintain compliance and efficiency.

Assistance Channels

The primary support channel for Defense Travel System (DTS) users is the Travel Assistance Center (TAC), which offers -wide assistance for unresolved travel issues, including DTS-specific problems such as difficulties, errors, and processing. TAC operates a tiered resolution process, beginning with self-service options like frequently asked questions (FAQs) and escalating to analyst intervention for complex cases, where tickets are routed based on category and resolved through direct support or further referral. TAC provides multiple contact methods, including a 24/7 phone line at 1-888-HELP1GO (1-888-435-7146) for immediate queries, though high call volumes may result in wait times. Users can also submit help tickets via the TraX portal within the Passport system, accessible at https://www.defensetravel.dod.mil/neoaccess/login.php, where detailed descriptions and screenshots aid in faster triage and status tracking. Additionally, live chat support is available Monday through Friday from 8:00 a.m. to 6:00 p.m. ET (excluding federal holidays) for common issues like profile updates and training certificates. For site-specific guidance, local assistance is available through roles such as the Lead Defense Travel Administrator (LDTA) and Organization Defense Travel Administrator (ODTA), who handle unit-level troubleshooting, access management, and compliance with local business rules before escalating to TAC. These coordinators, often embedded in military units or installations, provide tailored support for issues like travel determinations and system navigation. Online portals complement these channels: TraX enables ticket creation, monitoring, and access to policy alerts, while the Defense Travel Management Office (DTMO) at ://www.travel..mil/ offers clarifications on regulations, news feeds, and outreach resources such as scheduled calls for high-priority topics. Users are advised to review training materials as an initial step prior to contacting support.

Recent Updates and Future Outlook

2023-2025 Developments

In 2023, the (DoD) cancelled its $374 million MyTravel program, which had been developed over five years as a replacement for the Defense Travel System (DTS), due to low adoption rates and operational challenges. The cancellation was announced on May 24, 2023, with MyTravel operations officially ceasing on September 13, 2023, prompting a full return to DTS for all DoD travel management. From 2024 to 2025, DTS underwent targeted enhancements to improve functionality and compliance. In April 2025, the system was updated on April 9 to refine the constructed travel worksheet (CTW) process, adding clearer prompts and validation checks to determine when a CTW is required for indirect routes, thereby reducing errors in submissions. In August 2025, the "Create Your Own Expense" feature in DTS vouchers was replaced with seven predefined expense categories aligned to the Joint Travel Regulations (JTR), effective August 19, to standardize claims and minimize unauthorized reimbursements. Policy integrations during this period included revisions to JTR supplements addressing tours outside the continental (OCONUS), with updates published in February and July 2025 to incorporate new criteria for tour lengths and duties based on evolving operational needs. Additionally, the DTS Best Practices Guide was revised in July 2025 to expand guidance for non-government users, including contractors and invitees, on access levels, authorization processes, and compliance requirements within DTS. These developments are intended to enhance overall compliance by curbing improper claims and streamline through intuitive interfaces. As of November 2025, DTS remains fully operational, with a scheduled maintenance downtime from November 21 to 22, 2025, limited to routine security patches and no major disruptions reported.

Planned Enhancements

Following the cancellation of the MyTravel modernization project in May 2023, which was intended to replace the Defense Travel System (DTS) with a commercial software-as-a-service solution, the Department of Defense has shifted focus to sustaining and incrementally enhancing the existing DTS platform. This approach prioritizes cost efficiency, system reliability, and alignment with Joint Travel Regulations without a full overhaul. A primary planned enhancement is the continued transition of DTS to a cloud-based , aimed at improving system availability, scalability, and operational efficiency for its 2.9 million users. This migration, supported by contracts for , , and , is projected to complete key phases in 2026, with funding adjustments reflecting reduced reliance on legacy support services. The Defense Travel Management Office (DTMO) targets maintaining 98.5% system availability through these upgrades, enabling better handling of authorizations, vouchers, and reimbursements amid increasing travel volumes. Additional planned enhancements include ongoing refinements to user interfaces and policy integrations to reduce errors and unauthorized expenses. For instance, future iterations will build on 2025 updates, such as expanded expense categorization and automated prompts for constructed travel worksheets, to further streamline and processes. The FY2026 allocates resources for analyzing potential next-generation travel management systems, ensuring long-term adaptability while supporting current operations.
