had jets, their airplanes were called Flagships. I think the DC-3 at the AA
museum outside DFW
is Flagship Knoxville.
When the 707s were first delivered, they were Jet Flagships. Then, the moniker was changed to Astrojet, reflecting a modern theme.
I don't know if widebodies were ever referred as Astroliners. I don't think so, but I'm not positive. But with the current paint scheme, the terms Luxury Jet and Luxury Liner were introduced.
I firgured it was a matter of time before the names disappeared, because the 737-800s and the 777s never carried the decals.
