Tarmac delay rules are for foreign airlines at US airports? Outbound only, not inbound?
U.S. Department of Transportation Expands Airline Passenger Protections | Department of Transportation
Tarmac Delays. The new rule expands the existing ban on lengthy tarmac delays to cover foreign airlines’ operations at U.S. airports and establishes a four hour hard time limit on tarmac delays for international flights of U.S. and foreign airlines, with exceptions allowed only for safety, security or air traffic control-related reasons. Carriers must also ensure that passengers stuck on the tarmac are provided adequate food and water after two hours, as well as working lavatories and any necessary medical treatment.
The extended tarmac delays experienced by passengers on international flights operated by foreign carriers at New York’s JFK Airport during the December 2010 blizzard was an important factor in the Department’s decision to extend the tarmac delay provisions to foreign air carriers and establish a four hour tarmac delay limit for international flights.
