I do remember as a teenager flying down to LHR on a BEA Trident then taking a double decker bus into the centre of London....whereabouts in London I don't remember.

My earliest memories of flying were from the Art Deco styled Renfrew Airport which served Glasgow before Abbotsinch was built. There used to be a BEA office outside the rather grand St Enoch Station where you could take the coach to the airport. You can see it in the bottom right of this photo although that looks a bit before my time I have to say.
