Braniff Inc (also known as Braniff II), the reincarnation of the failed Braniff airlines had hubs in Kansas City, Miami and DFW. With a single class of service and all leather seating. They were focused on unrestricted low cost fares for every flight.
Braniff A320 – Wikipedia
This timetable is effective July 1, 1988, just a year before bankruptcy and finally suspending airline operations in November 1989. The route map is interesting as you don’t often see a Kansas City hub on any other maps.
Looking at a typical flight listing from New York (Laguardia) to Las Vegas shows:
4:05pL 7:41p 521/541 Daily MCI S
Which reads: depart at 4:05pm and arrive at 7:41pm. Flying flight 521 from LGA to MCI then flight 541 from MCI to LAS. Snack.
Braniff, in all it’s incarnations, was a well regarded airline with great customer service. However deregulation forever changed the airline no matter what changes they made.
