Managing Your Official Travel Within DTS

Addressing Access Difficulties in Your Travel Portal

⚠️ Cannot log in or profile not found

Cause: Incorrect organizational information or profile not activated.

Solution: We know being locked out is stressful. First, contact your Defense Travel Administrator (DTA) immediately. They can verify your account status, ensure your profile is linked to the correct organization, and activate it if needed. DTS account creation or activation is usually handled during organizational check-in.

⚠️ Browser compatibility issues

Cause: Your web browser does not meet DTS requirements.

Solution: Ensure your web browser is fully compatible. Check that JavaScript is enabled, cookies are allowed, and pop-ups are not blocked. Your DTA can assist with specific browser settings or direct you to compatibility guides.

⚠️ Password reset for non-CAC access (if applicable)

Cause: Forgot username/password for specific DTS Connex or similar applications.

Solution: If you are using a login other than CAC (e.g., username/password for DTS Connex), select 'I am having trouble logging in' on the specific login page to initiate a password reset. If issues persist, contact your organization's DTS administrator.
