Sec. 301-10.135  When must I travel using U.S. flag air carrier service?

    You are required by 49 U.S.C. 40118, commonly referred to as the 
``Fly America Act,'' to use U.S. flag air carrier service for all air 
travel funded by the U.S. Government, except as provided in Sec. 301-
10.136 and Sec. 301-10.137 or when one of the following exceptions 
applies:
    (a) Use of a foreign air carrier is determined to be a matter of 
necessity in accordance with Sec. 301-10.138; or
    (b) The transportation is provided under a bilateral or multilateral 
air transportation agreement to which the United States Government and 
the government of a foreign country are parties, and which the 
Department of Transportation has determined meets the requirements of 
the Fly America Act; or
    (c) You are an officer or employee of the Department of State, 
United States Information Agency, United States International 
Development Cooperation Agency, or the Arms Control Disarmament Agency, 
and your travel is paid with funds appropriated to one of these 
agencies, and your travel is between two places outside the United 
States; or
    (d) No U.S. flag air carrier provides service on a particular leg of 
the route, in which case foreign air carrier service may be used, but 
only to or from the nearest interchange point on a usually traveled 
route to connect with U.S. flag air carrier service; or
    (e) A U.S. flag air carrier involuntarily reroutes your travel on a 
foreign air carrier; or
    (f) Service on a foreign air carrier would be three hours or less, 
and use of the U.S. flag air carrier would at least double your en route 
travel time; or
    (g) When the costs of transportation are reimbursed in full by a 
third party, such as a foreign government, international agency, or 
other organization.
