2)        If a U.S. flag air carrier offers nonstop or direct service (no aircraft change) from your origin to your destination, you must use the U.S. flag air carrier service unless doing so would extend your travel time, including delay at origin, by 24 hours or more.

3)        If a U.S. flag air carrier does not offer nonstop or direct service (no aircraft change) between your origin and your destination, you must use a U.S. flag air carrier on every portion of the route where it provides service unless, when compared to using a foreign air carrier, doing so would:

4)        For all short distance travel, regardless of origin and destination, use of a foreign-flag air carrier is permissible if the elapsed travel time on a scheduled flight from origin to destination airport is three hours or less and service by a U.S.flag air carrier would double the travel time.
