3. In 1968, this air carrier advertised it was operating ten roundtrip flights a day between Los Angeles (LAX) and Las Vegas (LAS). The same aircraft type was operated on all of these flights. Identify the airline and the equipment.
I saw this and my first thought was Bonanza - but that would depend upon when in 1968 as the merger to form Air West also happened then. For now though, I'm going to counter jrl767's Western flights with Bonanza operating DC-9-10s...
