Mine would be from my timetable collection:
United Airlines timetable: 1/31/73
This was the UA timetable that was effective when I was born.
Allegheny Airlines timetable: 9/5/79
This would be the last timetable for Allegheny, which would become US Air. The front cover boldly states: "Starting October 28, Allegheny's growing into US Air." The inside of the timetable feature ads promoting the new airline.
United Airlines timetable: 10/1/84
Front cover has a beautiful aerial view the two WTC towers.
How terribly ironic.
United Airlines timetable: 9/5/01
This would be the last paper timetable to be printed by United Airlines. It was also the timetable that was effective during the 9/11 terror attacks.
Pan Am timetable: November, 1973
As with most Pan Am timetables of the early '70's, this shows scheduled service to: Beirut, Lebanon; Damascus, Syria; Tehran, Iran; and Karachi, Pakistan.
My my my, how things have changed.
