Jim McOmber collects flight schedules of two airlines; Braniff and Southwest Airlines. There is a finite number of Braniff flight schedules since they ceased operations in 1982 (Jim has almost all of them) and Southwest Airlines is the last of the big airlines that was still printing schedules. For Jim, his collection of airline flight schedules has come to an end. Pictured: Southwest flight schedule from 1975 showing back and front. It was the size of a double business card.
