There was something in the air in the early years of commercial aviation. Perhaps more excitement, perhaps more glamorous stewardesses... in any case, it's worth savoring once again.
In the 1950s, flying was an exotic and rare treat for most. In the '60s and into the '70s, flying became more affordable, and airlines began advertising more to the middle-class than the wealthy. Flying became a tad less formal; dressing up a bit was still expected, but full-on suit-and-tie was less common among pleasure-travelers.
During this time, airlines, particularly United, Eastern, Pan-Am and American, took to heavily promoting sex in their advertising. They portrayed Flight Attendants as sexy, cute, perhaps a bit dim. In short, they were portrayed as glamorous.
