What actions should a traveler take if their travel plans change after submitting an authorization?

When a traveler's plans change after submitting an authorization, the appropriate action is to modify or amend the authorization in TraX. This process ensures that the travel records remain accurate and up-to-date, reflecting the new travel arrangements. Modifying or amending the authorization in the system allows for proper tracking, compliance with travel policies, and ensures that any new expenses incurred are accounted for, facilitating reimbursement or other administrative tasks.

This approach also helps to avoid confusion and potential issues related to travel reimbursement or record-keeping later on. By maintaining accurate documentation through the approved TraX system, the traveler ensures that all changes are officially recognized and assisted by the necessary travel management frameworks in place.

The other options do not effectively address the responsibilities associated with managing travel authorizations in a systematic manner and may lead to complications in the travel management process.
