I pulled out an an old book I had not read in a long time, and tucked away in the middle was my ticket from a 1990 AS flight and a timetable/routemap from back then.
I found it fascinating to look at the AS route map from 21 years ago. How things have changed! It shows service to ORD and IAH/DFW, but that must have been the AA interchabge.
Thought others here might like to see it as well. You may need to zoom in to see the names of cities served.
