Which document must be included when requesting travel-related reimbursements?

When requesting travel-related reimbursements, including itineraries and boarding passes is essential because they provide verifiable evidence of the travel undertaken. Itineraries outline the details of the travel, such as dates, destinations, and modes of transportation, ensuring that the expenses align with the approved travel plans. Boarding passes serve as proof that the travel actually occurred, further confirming that the expenses being claimed are legitimate.

This requirement helps maintain accountability and transparency in the reimbursement process, ensuring that funds are used appropriately and within the regulations governing travel reimbursements. Providing adequate documentation is critical for fulfilling compliance and audit requirements, which can help avoid delays in processing reimbursements.

The other options do not adequately serve this purpose; for example, a request form alone would lack the necessary supporting documentation to validate any travel claims. Similarly, while a meeting agenda may be relevant to the trip context, it does not provide clear evidence of the travel itself. Telephonic approvals alone are not sufficient, as they do not create a concrete record of the actual travel activities.
