Which JTR reference allows travelers to receive reimbursement?

The JTR reference that allows travelers to receive reimbursement is generally JTR Chapter 2 for TDY travel and JTR Chapter 3 for PCS travel, with specific paragraphs authorizing per diem, transportation, and miscellaneous expenses. JTR is Joint Travel Regulations published by Defense Travel Management Office, and reimbursement authority comes from Title 37 and Title 5 US Code, implemented through JTR. For TDY, JTR 0201 to 0266 authorize per diem, lodging, meals, and incidental expenses, JTR 0202 authorizes transportation including airfare, rental car, and POV mileage, and JTR 0204 authorizes miscellaneous reimbursable expenses like baggage fees and parking. For PCS, JTR 0505 authorizes per diem and lodging, JTR 0506 authorizes transportation of dependents, and JTR 0513 authorizes DLA and other allowances. The key overarching reference is JTR 0101 which states travel must be authorized by orders, and reimbursement is allowed only when travel is under competent orders. Also JTR 0102 states traveler is entitled to allowances prescribed in JTR. For receipt threshold, JTR 0103 references 75 dollar rule. So travelers receive reimbursement when travel is authorized by orders and expenses are within allowances prescribed in JTR Chapters 2 and 3. The specific citation for reimbursement entitlement is JTR Chapter 2, Section 0203 for per diem and Chapter 2, Section 0202 for transportation, which allow travelers to claim actual expenses up to authorized rates. Finance offices use these references to approve vouchers in DTS.
