I always think of a Lockheed Constellation and TWA.
(Yeah, I saw "The Aviator" twice.)
The Constellation was a very cool plane. When I was about 5, my Dad moved us to Saudi Arabia, he worked for Aramco. Our flight was one of the last of the Constellation, the jets were pretty much taking over by then. Anyway, the flight was close to 20 hours, and we got to go 1st class (Aramco really paid well in those days). They actually had a chef on board, and for dinner they brought a giant roast on a cart to our seats and carved it right there for you.
I watched "The Aviator" at least twice. Man, wouldn't you love to have that plane with the cabin slung under the wing he was flying around in with Kate Hepburn? It was like a flying yacht.
