Pennsylvania Airlines - May, 1983

Pennsylvania Airlines flew under the Allegheny Commuter brand.

From Wikipedia:

The Allegheny Commuter division was originally headquartered at the Reading Airport in Reading, Pennsylvania, and flew a large fleet of Short 330s and Short 360s, being the launch customer for the Shorts 360. It had three Fokker F27 "Friendship" turboprops, and was the last US operator of passenger F27s. After replacing much of its Shorts fleet, and retiring the F27s, it merged with another fully owned USAir subsidiary, Pennsylvania Airlines, headquartered at Harrisburg International Airport near Harrisburg, Pennsylvania, and the combined airline retained the historic name until its own merger with another wholly owned subsidiary, Piedmont Airlines.

Golden West Airlines - March, 1983

This was likely the second-to-last or last timetable from Golden West, as it ceased operations in April, 1983. What's interesting about this timetable is that it features the tails from American, TWA, and United, but doesn't mention American anywhere else.
