There is nothing "full service" about any of the legacies anymore, except the fact that they all fully expect bailouts of taxpayer money to survive. For a domestic flyer the sad fact is that WN, B6, and VX all offer a better value and better service than any of the "full service" airlines.

If it were not for FFP's and people using corporate money (not their own) to stay loyal to these programs none of these airlines would survive, nor should they.
