| | j.� Foreign air carrier use is required to avoid an unreasonable safety risk (e.g., terrorist threats).� NOTE:� Approval based on an unreasonable safety risk must be in writing on a case by case basis.� Determination and authorization/approval of foreign air carrier use based on a threat against a U.S. flag air carrier must be supported by a travel advisory notice issued by the Federal Aviation Administration and the Department of State.� Determination and authorization/approval of foreign air carrier use based on a threat against Government employees or other travelers must be supported by evidence of the threat(s) that forms the basis of the determination and authorization/approval. |

| | l.� The total delay, including delay in initiation of travel from a TDY point, in en route travel and additional time at the TDY station before the traveler can proceed with assigned duties, involves more than 48 hours per diem costs in excess of per diem that would be incurred if noncertificated service was used (56 Comp.

| | m.� The only U.S. flag air carrier service between foreign OCONUS points requires boarding/leaving the carrier between the hours of midnight and 6 a.m., or travel spanning those hours, and a noncertificated carrier is available which does not require travel at those hours (the traveler may travel by noncertificated carrier to the nearest practicable interchange point on a usually traveled route to connect with a U.S. flag air carrier) (56 Comp. Gen. 629 (1977)). |

| | ---------------------------------------------------------------------------------------------------------------------------- | 
|
| | Schedules maximizing U.S. flag air carrier use must be selected.� Schedule selection is made using the following guidelines: | 
|
|

| |                                                                                                                                                                                                                                  | 
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | 
|
| | (1)� when U.S. flag air carrier service is available at the point of origin, schedules providing service by a usually traveled route, between origin and destination, and originating with a U.S. flag air carrier must be used; | 
|
|

| |                                                                                                                                                                                                                                                                                                                             | 
| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | 
|
| | (2)� when U.S. flag air carrier service is not available at origin or an interchange point, noncertificated air carrier service should be used only from point of origin to the nearest practicable interchange point on a usually traveled route, between origin and destination, to connect with a U.S. flag air carrier; | 
|
|

| |                                                                                                                                                                                                                                                      | 
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | 
|
| | (3)� when schedule selection leaves the traveler at a location from which there is no choice but to use noncertificated air between the U.S. and another continent, the travel should be rerouted so that available U.S. flag air carriers are used. |

|
| | Under the guidelines in subpar. a, the example schedule choice is limited to schedules II and III, because service is provided by a usually traveled route and originates with U.S. flag air carrier service.� Schedule III provides U.S. flag air service from Ankara via Istanbul to Frankfurt, while U.S. flag air service is available under schedule II between Ankara and Rome.� Schedule III should be selected because it uses U.S. flag air service to the farthest practical interchange point on a usually traveled route.� If the schedules in this example were limited to those shown in schedules I and IV, schedule IV would be selected since it clearly involves more travel by U.S. flag air carriers than does schedule I (See 55 Comp. Gen. 1230 (1976)). |

| | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | 
|
| | There is no reimbursement (for any leg of the journey) for transportation cost when unauthorized/unapproved foreign air carrier service is used.� If U.S. flag air carrier service is available for an entire trip and the traveler uses a foreign air carrier for any part or all of the trip, the transportation cost on the foreign air carrier is not payable (41 CFR �301-10.143). |
