Pan Am was a true airline in its day.
My first memories was seeing big large Pan Am aircraft model displays (707 usually) in their ticket offices growing up in Europe, but soon enough we were flying them.
PA's route global network stretched the world, and in many ways it was like coming home to a good fried to fly them, often in between two far flung exotic locales. I also remember making use of them intra-Europe quite a bit, and they were as competitive as any BA
/LH at the time.
For meals as with the times it was extensive, and on the 747s, you were invited upstairs to dine as if it was a restaurant. No feelings of having a crappy airline meal even in Y class. Even after deregulation it was not that bad, and I recall PA had very extensive specials meals. I recall ordering a seafood one which came with lots of crab.. yum yum.
By the end I was an Platinum level flyer in their WorldPass program. While the airline was certainly beyond its hey day, its extensive schedules to Europe in particular and its quite progressive business class product (2x2x2 seats on 747s) kept me loyal.
Looking back now, I can really say that flying was a different thing those days. Everything from going and waiting your turn at ticket offices to check on schedules (which were often only a couple flights per week) and buying tickets, to the more regal process of travel which seemed to be more of an affair then simply a bus like trip from point A to point B.
I will say though todays wide availability of travel choices, and certainly reduced cost is an overall improvement. I recall paying $800 one-way JFK
in the 1980s once for in Y-class for a same day booking!
