Open Skies Agreement
There are only four Open Skies Agreements that have been determined to meet the Fly America Act compliance requirements by the U.S. Department of Transportation.
The Open Skies Agreements do not apply if travel is funded by the Department of Defense (DOD) including the U.S. Military (Army, Navy, and Air Force).
Travel under certain Open Skies Agreements can be restricted if a City Pair rate is in effect for the specified travel route. If a City Pair rate is in effect, then travel must be provided by a U.S. flag air carrier, unless another authorized exception applies.
