It's time to close out my earlier survey based on the AA 1973 system timetable.
The unidentified city served nonstop from DAL with a DC-10 Luxury Liner was....MEM!
AA 264 left SFO 4:30 PM, arrived DAL 9:38 PM, left DAL 10:35 PM, and arrived MEM 11:47 PM.
AA's lone DC-10 flight from TUL flew TUL-OKC-LAX.
AA 147 left TUL 9:00 AM, arrived OKC 9:35 AM, left OKC 10:05 AM, and arrived LAX 10:45 AM.
AA's other 707 Freighter flight from Detroit went to Dallas. AA 837 left JFK 1:10 PM, arrived DTW 2:50 PM, left DTW 4:15 PM, and arrived DAL 5:32 PM. A big General Motors assembly plant was built in 1954 in Arlington, Texas. In 1973, it made GM's "A Body" cars like the Monte Carlo and Chevelle, but today it makes GM's biggest SUV's, like the Escalade and Yukon.
It's interesting that in 1973, AA did not have any 707F flights to either Los Angeles or San Francisco from Detroit, despite the large number of assembly plants at that time in those cities. However, both cities were served with 747s and DC-10s, so the auto parts were shipped as belly cargo.
