I think that it is clear that they intend to make change Delta from a "legacy" carrier into something that can can compete in the new century... it will be a company that operates fewer aircraft types for sure. I have felt for a long time that domestic FC was an obsolete concept (all the best customers expect to get it, but not to pay for it) , but perhaps a premium cabin will continue to exist, but with reasonable "A" type fares rather than the extreme F fares of the past.
