Northwest still has a hub in MEM
. It's not even just a regional hub either... they have flights to DC, NY, and the New England cities, and also to PHX
, and the West coast.
Perhaps we can soon add USAirways at PIT
How about Delta's mainline hub at DFW
? Due to competition from American, it's mostly CRJ's operated by ASA, Comair, and Skywest. Mainline Delta only goes to the big cities on or near the West coast, the major Florida cities, and the Delta hubs (ATL
), with very few others in between. They don't even have widebodies there anymore (or if they still do have a few now, they won't in a few months).
