What you're owed

Leaving Heathrow

£520each under UK law

Leaving New York (John F Kennedy)

£520each under UK law

New York (John F Kennedy) is outside the UK and EU, so coming back this only applies if a UK or EU airline operated the flight.

Heathrow to New York (John F Kennedy) is 5,540 km, which fixes the figure: £520 each leaving Heathrow, and the same £520 each coming back if a UK or EU airline operated the flight. It is per person, so four of you is £2,080.

How Delta Air Lines does on this route
