Which system would you refer to for the latest travel regulations?

The Joint Travel Regulations (JTR) is the authoritative source for the regulations governing travel for military and Department of Defense (DoD) personnel. It encompasses rules and guidelines related to travel entitlements, per diem rates, lodging allowances, and various travel processes specific to the military environment. Therefore, it is imperative for service members and authorized travelers to refer to the JTR for the most current and relevant travel regulations.

The Federal Travel Regulation System provides rules primarily for civilian federal employees, while Government Travel Guidelines may be too general and not specifically tailored to military travel. Travel Account Regulations likely focus on the financial aspects of travel accounts rather than the comprehensive travel procedures and policies, making them less relevant for inquiries about official travel rules. Thus, the JTR is the most suitable reference for the latest travel regulations.
