What should travelers do if they have unusual expenses reported in DTS?

Travelers should provide justification and documentation for any unusual expenses reported in the Defense Travel System (DTS) because these expenses need to be clearly understood and verified for reimbursement. Unusual expenses may not align with typical travel costs and could trigger questions or require additional scrutiny from approvers or finance personnel. By including justification and proper documentation, travelers can ensure that these expenses are accurately captured and approved, facilitating a smoother reimbursement process and helping to uphold the integrity of the travel system. Properly justifying expenses also demonstrates accountability and adherence to travel policies, which is essential in maintaining compliance with federal regulations and ensuring responsible use of government funds.
