Incidentally, a few years ago I flew back from Dulles (Washington) to Deathrow and managed to blag Upper Class (did a few favours when i was working at Dulles airport). Yes, admittedley you get a lot of legroom and I got a neck massage from a lovely Welsh girl, and yes, there was free Champagne (posh stuff too) and yes, you do get offered a handjob from all the male stewards...but all in all i was a bit disappointed. I believe my ticket should have cost somewhere in the region of 4k and to be honest it wasn't worth it. Luckily you, the British taxpayer, bought it for me...
Oh and when the menu came round for the evening meal it was a bit posh for me so i asked for a chicken dinner from economy
honestly!
