Areed. CO doesn't need anybody........they are probably the BEST US carrier operating in today's environment. A Delta-CO merger several years ago would have been good but not sure whether either would even consider it at this point. No way Parker gets his hands on CO.There is no way Doug will get his hands on CO. Larry Kellner and his team KNOW how to run a successful airline. They have happy labor for the most part, and VERY happy customers. Why would Larry let Doug lead?
That said, I can see Doug taking over NW, if/when it gets the west operation--now that is a real possibility.
I think the most logical sense comes of East-UA and West-NW. CO really doesn't need a partner right now, although they could be a backup to NW for the west.
IF a combination were to come involving CO, it would most likely be the CO way and culture which survives.
Then again, stranger things have happened......
