DTS Overview and Authorities
Plain-language walkthrough of the Defense Travel System (DTS) from a Marine traveler's perspective. DTS is the DoD-wide system for booking, claiming, and reconciling official travel. Authorized authorizations and post-travel vouchers flow through DTS. The Marine Corps program is implemented through MCO 4650.39A. Recent updates include MARADMIN 359/25 (OTO and zero-dollar voucher framework), MARADMIN 291/12 (DO/FO voucher approval routing), and MARADMIN 157/25 (IDT travel reimbursement). Per MCO 4650.39A, DODFMR Vol 9, JTR Chapters 4-5.
Start Here If You Are New to DTS
The Defense Travel System (DTS) is the DoD-wide system for booking official travel, submitting travel vouchers, and reconciling expenses with DFAS. Every Marine on TDY or PCS uses DTS to.
- Build the trip authorization before travel.
- Reserve airfare (City Pair Program), rental car (DoD Rental Car Program), and lodging. Marine Lodges and Inns of the Corps on Marine Corps installations are bookable in DTS effective 25 May 2026 per MARADMIN 234/26MARADMIN 234/26.
- Get the AO to approve the authorization.
- Submit the travel voucher within 5 working days of return.
- Receive reimbursement via EFT and split disbursement to Citi for GTCC charges.
The Marine Corps DTS program is governed by MCO 4650.39AMCO 4650.39A. The DTS Program Management Office (PMO) at HQMC P&R-RFF runs the program. Recent MARADMINs (359/25, 291/12, 157/25) update specific procedures. Per MCO 4650.39AMCO 4650.39A, DODFMR Vol 9DODFMR Vol 9, JTR Chapters 4-5.

What DTS Is
DTS is the Department of Defense electronic travel system. Every authorized DoD traveler uses DTS for.
- TDY trip authorization and approval.
- Travel reservations (airfare, hotel, rental car).
- Travel voucher submission and reimbursement.
- Government Travel Charge Card (GTCC) integration.
- Centrally Billed Account (CBA) reconciliation.
- IDT travel reimbursement (specific to SMCR Marines).
DTS is web-based at https://dtsproweb.defensetravel.osd.mil/. Marines log in with their CAC.
Why DTS Exists
Before DTS, official travel involved paper DD Form 1610DD Form 1610 authorizations, manual ticketing, paper receipts, and DD Form 1351-2DD Form 1351-2 vouchers submitted by mail or in person. DTS consolidates the workflow into one system that.
- Enforces JTR compliance during authorization creation.
- Books travel through Government-contracted vendors at the lowest available rates.
- Routes documents to the correct AO automatically.
- Calculates reimbursements and split disbursements.
- Interfaces directly with the accounting system (DAI for the Marine Corps).
- Reduces administrative time and paper.

DTS Integration With Other Systems
GTCC Integration
DTS uses the GTCC information from the cardholder's profile to.
- Book airfare via the City Pair Program.

- Book lodging at GSA per diem rates.
- Calculate split disbursement on voucher submission.

The DTS voucher reimbursement flows from DTS to DFAS to MyPay (LES). The cardholder's EFT bank account information drives the deposit destination for any portion not split-disbursed to Citi.
Defense Agencies Initiative (DAI) Accounting System
DTS authorizations and vouchers create obligations in DAI. The OTO management framework (MARADMIN 359/25MARADMIN 359/25) reconciles obligations between DTS and DAI.
MCTFS
The Marine Corps Total Force System provides the personnel data DTS uses for AO assignment, organization placement, and IDT eligibility (per MARADMIN 157/25MARADMIN 157/25).

Common Questions Marines Ask
What is DTS?
The DoD-wide electronic travel system for authorizations, reservations, vouchers, and reimbursement. Web-based at https://dtsproweb.defensetravel.osd.mil/.
What governs DTS at the Marine Corps level?
MCO 4650.39AMCO 4650.39A (Marine Corps DTS Program). Recent MARADMINs (359/25, 291/12, 157/25) update specific procedures.
Who runs the DTS program for the Marine Corps?
The DTS Program Management Office (PMO) at HQMC P&R-RFF. Contact OMB_HQMC_PR_RFF_DTS_GTCC@USMC.MIL.
How long do I have to submit my voucher?
5 working days from return per JTR Chapter 4 and DODFMR Volume 9DODFMR Volume 9. Late submission triggers ODTA outreach at day 5 and zero-dollar processing at day 30 per MARADMIN 359/25MARADMIN 359/25.
What is the difference between an authorization and a voucher?
The authorization is the pre-travel approval (covers planned expenses). The voucher is the post-travel claim for actual reimbursement. Both flow through DTS.
What happens if I do not submit my voucher?
Per MARADMIN 359/25MARADMIN 359/25, the ODTA contacts you. The NDEA submits a zero-dollar voucher at 30 days. The DTS PMO automates a zero-dollar voucher at 90 days. You may also lose reimbursement and risk GTCC delinquency.
How does DTS connect to my GTCC?
Your GTCC information is in your DTS profile. DTS books airfare, rental car, and lodging using the GTCC. The voucher calculates split disbursement to pay the GTCC bill directly from your reimbursement.
What is the City Pair Program?
A GSA-negotiated air fare program available through DTS. Lower than commercial fares, fully refundable, no advance purchase requirement. The GTCC TDY Use leaf covers City Pair in more depth.
