In yet another blow to US Airways, the NY Times reports that the airline is looking to sell off assets, including US Airways Express and the Shuttle. This, it certainly goes without saying, is not a good sign. Combine this with the airline’s inability to gain necessary concessions from labor (assuming this isn’t just a giant ploy to gain those concessions), Southwest’s entry into Philly, and the airline’s miserable relationship with Pittsburgh and you can see the mess is getting worse. If I had $125 million, I’d be setting up my low-fare high-image airline at Charlotte, where US Airways has 85% of the flights, right about now. With Southwest coming into the Philly hub, the Pittsburgh hub falling apart, Southwest taking over BWI, and the airline still losing money, how much cash would US Airways be willing to spend to fend off their last fortress?
