Another point, the flight was AWE1549. Note that AWE is the American West 'Cactus' callsign, rather than USA 'US AIR.'
The company, based in the Phoenix, Arizona area, within the past several months ordered all crews (USA and AWE) crews to use the Cactus call sign, not just the AWE crews. I guess that's part of the multi-year merging process.
But, this lead to HUGE confusion amongst air traffic controllers. They asked that if the USA crewed flights were going to use the Cactus call sign, that they also use the AWE identifier on their flight plans.
I doubt that Capt Sully ever has flown for the former AWE, since he flew for PSA, which was bought by USA in the 1980's. Same for the other crew members who came from Allegheny and Piedmont. I think the FO was the only crew member potentially hired directly by USA.
None of the crew members appear to have ever served as America West crew members.
