I have to say that the OP has some good points about the current status of CO. No one can deny that they are a very "what have you done for me lately" airline when compared to the other legacy carriers (no lifetime elite for x MM miles flown as a great example).
And whatever happened to the whole idea of buying a premium ticket for the entire experience, not just a wider seat with free alcohol? I think those were the burried messages of the first two posters. I could be wrong, though...
