London Heathrow lives in the suburbs of London and so can technically call itself a London Airport.
London Gatwick, however is half way between London and Brighton.
London Oxford, near where I live is nowhere near London.
I once flew to London Glasgow Airport with RyanAir, I thought that was pushing the boundary.
Today I learned of Eday London Airport which lies on the remote Scottish Orkney Island islands.
If you were to drive from Eday London Airport to London, with correct Ferry timings it would take around 16 hours.
