There is really nothing left of the PSA/USAir merger from 1988.
In 1991 USAir vacated the former PSA route system except for LAX-SFO flown on mainline and a few commuter flights operated by Trans-States as USAir Express.
Ultimately,USAir vacated those markets as well. All that remained was transcon service from SEA,SFO,LAX,SAN,LAS,and PHX to USAirways PIT,PHL, and CLT hubs. These have also been trimmed to just a few flights per day.
All that remains are the small cadre of former PSA employees. And we are looking forward to seeing that PSA Retro-Jet in a West Coast city soon. Especially San Diego, birthplace of the original LCC, 6 MAY 1949!
