The best time I've ever had in a passenger jet was JFK to London. Nice, comfortable plane, no idea what kind, but had plenty of room, my own mini tv in the front of my chair with 12 or so movies to choose from, free headphones, large lavatory, free booze (wine*), and actually a pretty decent pasta dish, and the stewardesses are friendly. All this in the cheap seats.
Went to England, spent a fortune, and had a grand old time. I was looking forward to the flight back and all the nice pampering.
UNFORTUNATELY.... Once they've got yer cash and you're on your way back home, it's down to a crummy plane, no personal tvs (still free headphones at least), stuck watching a presentation of guacomole (I'm serious), tiny bathroom, booze costs money, you get a cold cut sandwhich, and no one cares how yer doin'.
I had to feel bad for the British tourists. Whereas I had all of the former plus a kind reception in "customs" going to England (talked to one lady for a minute or so, no line), they had all of the latter, plus our own, post-9/11 version of "welcome" coming here.
