Federal employees and invitational travelers: Start with your agency’s travel policy manager. Each agency has one. The Federal Travel Regulation is available on ecfr.gov, and we provide additional information on gsa.gov. The FTR also provides information on challenging a disallowed claim.
Federal contractors: Seek guidance from your contracting officials.
Non-federal travelers: We're unable to offer policy guidance. Direct your question to your travel management or human resources office.
