What to know
JFK official airline directory lists British Airways at JFK. Terminal operations can move during construction, irregular operations, or seasonal schedule changes.
Airport layout
JFK's active passenger terminals are 1, 4, 5, 7 and 8. AirTrain connects the terminals outside security; changing terminals normally means clearing security again.
Getting to the gate
Confirm both the airport code and terminal. New York itineraries can use JFK, LaGuardia or Newark, which are separate airports.
Connections
Leave a generous buffer for a terminal change because there is no universal airside connection among JFK terminals.
