Well my last (and only) recollection of Pan Am was flight from LAX on a standby ticket in 1979. Even then their CC had the reputation of being the oldest in the business (one would like to think that they equated experience with quality of service.....)
However, that trip was memorable for a 'Dirty Harry' type LAPD officer sporting some sort of long barreled magnum whilst trying to chat up the check-in staff (he clearly thought size did count) and a disgruntled US customer jumping on to the desk to shout that he would never use Pan Am again. Can't remember what caused the mayhem (having spent the day in the bar waiting) but glamorous it certainly wasn't.
