(a) Except as provided in paragraph (b) of this section, this part applies to U.S. certificated air carriers, U.S. commuter air carriers and foreign air carriers that operate passenger service to or from a U.S. airport with at least one aircraft that has an original manufacturer's design capacity of 30 or more seats. Covered carriers must report all passenger operations that experience a tarmac time of more than 3 hours at a U.S. airport.
(b) For foreign air carriers that operate charter flights from foreign airports to U.S. airports, and return to foreign airports, and do not pick up any new passengers in the U.S., the charter flights are not flights subject to the reporting requirements of this part.
(c) U.S. carriers that submit Part 234 Airline Service Quality Performance Reports must submit 3-hour tarmac delay information for public charter flights and international passenger flights to or from any U.S. large hub airport, medium hub airport, small hub airport and non-hub airport. These carriers are already required to submit such information for domestic scheduled flights to or from U.S. large hub airports under art 234 of this chapter. These carriers that are covered by part 234 need only submit information for flights with tarmac delays of more than 3 hours under this part 244 for domestic scheduled passenger flights to or from any U.S. medium hub airport, small hub airport and non-hub airport to the extent they do not report such information under 14 CFR 234.7.
