| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | 
|
| | e.� Foreign air transportation is fully paid for directly, or later reimbursed by a foreign government, an international agency, or other organization. (B-138942, March 31, 1981 and 57 Comp. Gen. 546 (1978)); NOTE: See Security Assistance Management Manual, Chapter 2, par. 20202-C3e of the DoD 5105.38-M, when travel is on Security Assistance Business. |

| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | 
|
| | f.� If a U.S. flag air carrier offers nonstop/direct service (no aircraft change) from origin to destination, U.S. flag air carrier service must be used unless such use would extend travel time, including delay at origin, by 24 hours or more. |
