I would say up untill 1990. First class lived up to it's name and flying was a privelige for the wealthy. Stewardesses were dressed up like no one else(this being a good thing) they didn't have an attitude, they smiled. Flying was luxurious then. Also, 1969-1990 you had classic 747s,L1011,DC10,MD-11. Pan Am,Eastern,Braniff,TWA were flying.
Give me a break, I created this username when I was a kid...
