Dan Air were always good, but I have to confess a sweet-spot for BA.
Mid cruise as a youngster I asked the cabin-crew if it would be possible to go upfront. Yes came the reply and after a few minutes talking to the Captain, he asked if I would care to stay and take the jump seat for landing.
That first jump-seat flight in a BA757 on a winter's afternoon coming into Heathrow, as the sun was setting. The dusk over London and then the right turn onto 27R, with the runway lights lit up. Even now, I can still remember the stand!
