Now that was very much a no-frills airline.
They did charge a bag fee but it was only $2 a bag at the time. You could buy beers on board for just a dollar. You could bring your own peanuts.
The stewardesses were very much "girl next door" in that they were not glamorous in any way but very much polite.
The pilots were entry level but they seemed to have at least some military experience and you did not feel unsafe with them flying the plane.
The people at the gate were exceptionally rude but what could you expect from a super cheap airline in which you could fly from Boston to Los Angeles for just $69?
They went bankrupt by the end of the 1980s and ended up getting absorbed by Continental, but they had only one major mishap, due to an improperly sealed milk carton, if I remember correctly.

We were in Baltimore back in the 80s and looking to fly on Peoples Express. Couldn’t find the desk so I went up to another counter & they said it was around the corner. Went to look & it was a portable kiosk that they rolled out prior to a flight. We didn’t fly.
