Here's a couple from the March 15 1974 OAG...
1.) Which airline operated twice daily 747 service between Chicago and Miami?
2.) Which airline flew once a week 747 service between Houston and Los Angeles?
3.) Which airline flew 1 stop DC-10 service between Phoenix and Los Angeles? Where was the stop?
4.) Which airline flew a once daily 747 flight between Chicago to Tampa?
5.) Not including Eastern, which may or may not have kept a couple of Electras on hand to fill in on shuttle operations, name three North American airlines that still operated scheduled seervice with Lockheed Electras in 1974.
