What Is Defense Travel System Explained Simply
The Defense Travel System (DTS) is the online tool you use to plan, authorize, book, and get reimbursed for official DoD travel quickly and by policy. You’ll create travel authorizations, pick government fares, use your CAC to sign in, and upload receipts for vouchers. DTS tracks spending, enforces rules, and helps speed approvals so travel pays out correctly and is auditable. Keep going and you’ll find practical steps, access tips, and troubleshooting help.
What Is the Defense Travel System (DTS) and Why It Exists

Think of the Defense Travel System (DTS) as the Pentagon’s online tool for planning, authorizing, and reimbursing official government travel—you use it to request orders, book transportation and lodging, and file vouchers so you get paid back.
It standardizes expenses, enforces policy, speeds approvals, and tracks spending. You follow rules, attach receipts, and rely on DTS to guarantee accurate, auditable travel payments.
Who Uses DTS: Service Members, Civilians, and Contractors
Users of DTS include military service members, civilian employees, and certain contractors who perform or support official travel.
You use DTS to request approval, book travel, and submit vouchers. Roles determine access and entitlements, and you follow agency rules and audit requirements.
- Service members: operational and PCS travel
- Civilians: official business and training
- Contractors: authorized mission support
Where DTS Fits in the DoD Travel Workflow
You’ll see DTS sitting at the center of the DoD travel workflow, handling orders, reservations, and reimbursements from start to finish.
It talks to other DoD systems—personnel, finance, and transportation—to pull approvals and push payment data.
Understanding that placement and integration helps you follow how a trip moves from request to paid claim.
DTS Placement In Process
When your unit schedules travel, DTS steps in after authorization but before final payment—it’s the central system where you create authorizations, record expenses, and submit vouchers for reimbursement.
You use DTS to document orders, track spending, and request advances so finance can process settlements efficiently.
- Create authorization
- Record expenses and receipts
- Submit voucher for payment
Integration With DoD Systems
After you create authorizations and submit vouchers in DTS, the system connects with several Defense Department platforms to move orders, payments, and personnel data along the travel workflow. You’ll see approvals, payroll updates, and audit records flow automatically, reducing manual steps and errors.
| System | Role |
|---|---|
| DFAS | Payments |
| EHR/HR | Personnel |
How to Get DTS Access: CAC, Account Setup, and Profile
Getting DTS access starts with three clear steps: obtain a valid CAC, set up your DTS account through your unit or travel office, and complete your user profile so the system recognizes your rank, pay, and entitlements.
Getting DTS access is simple: obtain a CAC, have your unit activate your account, and complete your profile.
- Visit your RAPIDS/CAC office to get or renew your card.
- Request account activation from your unit or travel office.
- Log in, verify personal data, and enter pay/entitlement details.
DTS Essentials: User Roles, Permissions, and Profiles
Now that you’ve set up your DTS account, you’ll want to understand the different user roles and what each one lets you do.
Permissions control tasks like creating authorizations, approving travel, and accessing traveler records, so knowing your profile’s rights saves time and prevents errors.
Check your profile early and ask your admin to adjust roles or permissions if something’s missing.
User Roles Overview
Roles define what you can do in DTS, so it’s important you understand them: each role grants specific permissions—like creating travel authorizations, approving claims, or managing profiles—and your combination of roles determines the tasks you’ll see and the actions you can take.
- Traveler: submit authorizations, file vouchers.
- Approver: review and authorize traveler requests.
- Admin: assign roles, monitor system activity.
Permissions And Profiles
You’ll be assigned a role (traveler, authorizing official, voucher approver) and a profile that bundles permissions.
Check your profile if features are missing, request adjustments through your agency helpdesk, and limit permissions to what’s necessary for security and compliance.
Preparing for TDY: Required Documents and Policy Checks
Before you depart on TDY, gather the documents you’ll need and verify policy details so travel approvals and reimbursements go smoothly.
Before departing on TDY, gather required documents and confirm policies to ensure smooth approvals and reimbursements.

Follow local and DoD-specific guidelines to avoid delays.
- Orders and ID
- Receipts and authorization forms
- Per diem and lodging policy
Creating a Travel Authorization in DTS
Now you’ll start a Travel Authorization in DTS by creating a new authorization and selecting the TDY type.
Enter the traveler’s information, travel dates, funding citations, and any required entitlements.
When everything looks correct, submit the authorization for approval so your chain of command can review and certify it.
Start A Travel Authorization
When you’re ready to create a Travel Authorization (TA) in DTS, you’ll open the system, select “Create New Authorization,” and follow the guided form to enter trip details, travelers, and funding information.
Proceed deliberately, save often, and verify approvals before submission.
- Choose itinerary and dates.
- Assign funding/source.
- Attach required documents and remarks.
Fill Traveler Information
Enter each traveler’s personal and duty-related details carefully so DTS can calculate entitlements and route approvals correctly.
You’ll provide name, rank, SSN or DoD ID, contact info, duty station, and travel purpose.
Specify dates, traveler type (government cardholder or not), and any special allowances or attachments.
Double-check accuracy to prevent reimbursement delays and routing errors before moving on.
Submit For Approval
Start the authorization by reviewing every section for accuracy—dates, locations, traveler type, and cost estimates—then click Submit for Approval to send the package into the routing queue.
You’ll get confirmations, can monitor routing status, and must respond to any amendments.
Verify receipts and justifications are attached before submission.
- Confirm accuracy
- Attach documents
- Monitor status
Amending or Correcting an Approved Authorization in DTS
Need to change something on an approved authorization? You can amend or correct it in DTS by creating an amendment request or recalling the authorization if allowed.
Update dates, purpose, or funding details, attach justification, and resubmit for approval.
Small corrections may be handled administratively; significant changes need approver review.
Always document reasons and keep records for audit.
Per Diem, Lodging, and Meals in DTS
Per diem rates in DTS determine what you’re reimbursed for lodging, meals, and incidental expenses while traveling on official duty; they vary by location and travel dates, so check the applicable rate table before booking.
Per diem rates in DTS set your lodging, meal, and incidental reimbursements—check location and date-specific tables before booking.
You’ll book within allowed lodging caps, claim meal reimbursements, and document receipts as required.
- Follow locality caps.
- Track meal splits.
- Upload receipts promptly.
Requesting Travel Advances in DTS
If you’re going to incur out-of-pocket expenses before your trip, request a travel advance in DTS to cover anticipated costs like lodging, meals, and authorized incidentals.
Advances are optional, require justification, and must be reconciled with actual expenses after travel.
Submit advance requests with estimated amounts and supporting rationale, get required approvals, and track disbursement.
After travel, promptly reconcile and return any excess funds or document shortfalls.
Booking Flights, Rentals, and Rail Within DTS
When you book flights, rental cars, or rail tickets in DTS, start with a complete travel authorization and select options that meet JTR entitlements and mission needs.
The system will show government-negotiated fares and allowable rates, so pick the lowest-cost, mission-appropriate choice and document any exceptions for approval.
Select the lowest-cost, mission-appropriate government-negotiated fares and allowable rates; document any exceptions for approval.
- Compare authorized carrier and fare options.
- Choose allowable rental class and insurance.
- Save receipts and justify deviations for approvers.
Using the Government Travel Charge Card and Split Disbursement
You’ll usually use a Government Travel Charge Card (GTCC) to pay for authorized travel expenses, so you’ll need to know the basics like card setup, authorized charges, and billing rules.
DTS lets you select split disbursement so the agency pays the card issuer directly while any remaining reimbursement goes to you.
We’ll walk through how to enable split disbursement and what to watch for when using the GTCC.
Gov Travel Card Basics
A government travel charge card streamlines paying for authorized expenses on official trips and helps you avoid out-of-pocket charges by billing the agency directly for preapproved costs.
You’ll use it for lodging, transportation, and meals; follow agency rules, reconcile statements promptly, and avoid personal charges.
Keep receipts and monitor account activity to prevent delinquencies.
- Card use
- Reconciliation
- Documentation
Split Disbursement Process
Because split disbursement automatically sends your agency’s authorized travel reimbursements directly to the government travel charge card, you won’t have to pay approved charges out of pocket or manually settle the bill after travel.
You’ll select split disbursement when filing vouchers; the government pays card charges directly and refunds any remaining balance to you.
Monitor statements to confirm payments and resolve disputes promptly.
Uploading Receipts and Required Documentation Correctly
Start by gathering every receipt and document the DTS requires before you begin your voucher so you won’t interrupt the upload process.
Scan legible copies, name files clearly, and match items to line entries. Follow DTS file-type and size limits, and attach mandatory authorizations.
- Itemized receipts
- Approvals and orders
- Proof of payment
Submitting a Reimbursement Voucher in DTS
Now that your receipts and documents are uploaded, you’ll prepare them for the voucher by grouping and labeling each expense clearly.
You’ll complete the voucher details in DTS, matching amounts and dates to your receipts and adding any required explanations.
Before you submit, review for accuracy so the payment isn’t delayed.
Preparing Your Receipts
Gather the receipts you’ll need for your reimbursement voucher and organize them by date and expense type so you can upload them quickly into DTS.
Scan or photograph each receipt clearly, label files with dates and categories, and keep originals until reimbursement posts.
Follow these steps:
- Verify merchant, amount, and date.
- Match receipts to itinerary legs.
- Rename files for easy upload.
Completing Voucher Details
Open your voucher in DTS and work through each section methodically, entering trip dates, travel allowances, and expense line items exactly as they appear on your receipts and itinerary.
Attach scanned receipts, select appropriate accounting codes, explain any discrepancies, and claim per diem correctly.
Review totals, verify advance repayment, and submit.
Monitor approval status and respond promptly to reviewer requests to avoid payment delays.
Typical Timelines: Authorization to Reimbursement
Because timelines can vary by duty station and approval level, you’ll want to track key milestones from authorization through final reimbursement.
You should monitor submission, approval, travel completion, voucher submission, and disbursement dates to spot delays and follow up promptly.
- Request authorization and note approval deadline.
- Complete travel and file voucher within entitlement window.
- Track payment posting and escalate if overdue.
Approval Routes and Who Signs DTS Authorizations
Now you’ll learn how authorization routing works in DTS and who signs off at each step.
You’ll see the typical approval flow, the roles approving officials play, and how signature authority levels determine who can approve or certify your authorization.
Understanding these points helps you route requests correctly and avoid delays.
Routing And Approval Flow
When you submit a DTS authorization, it follows a predefined approval route so the right people review and sign off at each step; that route depends on your agency, the trip type, cost thresholds, and any special travel approvals required.
You’ll see sequential reviewers, conditional routes for high-cost or TDY, and notifications when action’s needed.
- Originator to supervisor
- Routing manager or cost center
- Final approving official
Approving Officials Roles
1 key thing to know about approving officials is that each role in the route carries a specific authority and decision point—you’ll see supervisors verify mission necessity, routing managers check budget and coding, and final approving officials assume legal and fiscal responsibility before travel is authorized.
You’ll review who signs at each step, respond to queries, and guarantee authorizations move promptly through the correct approval path.
Signature Authority Levels
Because each DTS authorization follows a defined approval route, you’ll always know who’s signature authority at every step and what decision they’re responsible for.
You’ll see levels tied to cost, mission impact, and security classification.
Reviewers sign for accuracy; approvers validate necessity; final authorizers confirm fund availability.
- Reviewer: accuracy check
- Approver: mission necessity
- Authorizer: funds/security
Handling TDY Extensions, Cancellations, and No-Shows
If your TDY plans change, you’ll need to update DTS promptly so travel orders, entitlements, and reimbursements stay accurate. Notify your approving official, amend orders for extensions, cancel unused reservations, and document no-shows with reasons and supporting evidence to avoid debt or audit issues.
| Action | Who to Notify | Evidence Needed |
|---|---|---|
| Extend | Approver | Updated orders |
| Cancel | Travel office | Cancellation receipts |
| No-show | Approver | Explanation, proof |
Special Cases: Joint Travel, Foreign Travel, CONUS vs OCONUS
Changes like extensions or cancellations also affect special-case travel rules, so you’ll want to handle Joint Travel, foreign trips, and CONUS vs OCONUS moves with the same prompt updates and documentation.
You’ll check authorization for dependents, status, and host-nation requirements; update per diem and routing; and keep records for audits.
- Joint travel coordination
- Foreign-entry/visa checks
- CONUS vs OCONUS entitlements
How DTS Enforces Policy and Flags Common Errors
When you enter a travel claim in DTS, the system actively enforces policy by validating entitlements, routing approvals, and flagging discrepancies against governing regulations; it won’t let you finalize a voucher that violates allowances or missing required authorizations. You’ll see real-time warnings for rate errors, missing receipts, and routing failures, prompting fixes before submission.
| Error | Indicator | Action |
|---|---|---|
| Rate exceeded | Red flag | Adjust claim |
| Missing receipt | Yellow | Upload |
| Approval gap | Alert | Route |
Troubleshooting Frequent DTS System Messages
Because DTS shows a lot of different warnings and errors, you’ll want a straightforward way to identify what each message means and what to do next.
Use concise steps to resolve common alerts and keep travel moving.
- Check message code, read the help link, apply the policy fix.
- Re-enter or attach missing documents, then revalidate.
- Contact your approving official or helpdesk with screenshot and steps taken.
DTS Integrations With Airlines and Defense Finance Systems
Although DTS runs on its own interface, it links directly with airline reservation systems and Defense Finance and Accounting Service (DFAS) feeds so you get up-to-date ticketing, itinerary, and payment information automatically; you’ll see reservations, E-ticket numbers, and traveler reimbursements sync into DTS and DFAS without rekeying.
You can verify tickets, authorize changes, and guarantee payments route correctly, reducing errors and speeding reimbursement.
