Delta pushing TUL-ATL flights to ASA. Equipment also changing: 737s to 70 seat, Canadair regional jets.
My opinion, FWIW: they're keeping the route and number of flights, which is the primary thing to worry about. If anything, pushing it down to a to a carrier with more efficient equipment actually cements it. Plus, the rj is a nicer, quieter, quicker ride than a 737.
