American, Continental and TWA

Correctamundo! It was the Proud With The Golden Tail

11. Which U.S. airlines were operating 720s on the November 15, 1970 schedule?

Alaska, American, Braniff, Continental, Northwest, United and Western

Northwest is the right choice as Eastern had divested itself of its 720s shortly before this OAG was published. I did a bit of research on Alaska Airlines though (since its flights were listed under equipment as "JET"). Alaska did not take delivery of its first 720 until April 1973. All of the 720s were purchased from other airlines (WA -ex PNA, BN and UA) and were not used past 1975.

13. By 1970, only one airline still flew Lockheed Electras to and from Seattle. Name the airline and the single route served.

Western: Kodiak-Seattle nonstop

Right again! Back then, Western's Electra was The Only Way To Fly between Seattle and Kodiak (Twice weekly service). Ten years later I flew the same route aboard a Wien Air Alaska 737-200.
