This is a 59 page American Airlines timetable which has a route map as you open the timetable.
There were an internationl carrier then was flights to Mexico City, Acapulco, Bermuda and eight Caribbean cities.
I liked AA timetables of the era as they showed what aircraft was used on each flight. This timetable shows they flew 727, 707, DC10, and 747 aircraft.
The 747's were used between JFK and LAX/SFO/SJU. DC10's were used to bigger cities including Buffalo, New York.
This was also a time with the major airlines had cargo only jets with AA using 747's and 707's. This timetable also showed their freight schedule. Most freighter service was to New York/JFK/EWR, Chicago, Philadelphia, Detroit, Cleveland, San Juan, Dallas, Los Angeles, and San Francisco.
