This could be a distinct possibility. Remember that DL and NW called off their merger, only to announce it again a few weeks later. Anything can happen.
I must say that I am disappointed. I think CO will do well because of their culture and management. They are the one airline out there right now who understands a service industry, and it shows in their employees and product. Kudos for them.
Unfortunately for UA employees, as long as Tilton is at the helm and hell bent on consolidation, we will be forced to deal with the train wreck known as USAirways.
Oh get over it already, UAL, AA, DAL, CAL - is no better than US --- US emloyees are good employees, that have been managed by morons, kinda like Tilton... Wake up and pray hard for good management and you will have great employees that will work hard for you.. Otherwise you are doomed.
