Ouboy- I used to live in Atlanta, and I have been to Birmingham a few times and have also flown out of BHM on WN. I do concur that there is a big banking industry in Birmingham, but the problem with BHM is that the big banking industry is it, theres not much else. A couple upper class neighborhoods around BHM is the only thing sustaining DLs service, which is the largest full service carrier at BHM. Besides DL, all of the other carriers do not aim to serve local traffic for the most part. WN does well there for a reason, it is a low-yield city. BHM will not gain much more service for that reason.
As for airports in the northeast, I am shocked that no one has attempted to start some service out of Bridgeport. Bridgeport may not be the richest place in the world, but Fairfield County certainly is! For a traveler living in Westport, Fairfield or Easton, they are forced to drive the 1.5 hr. to LGA. Or they could drive the 20-30 mins. to Bridgeport. US Airways Express used to serve BWI and PHL from Bridgeport (I flew there once, but I have totally forgotten the airport code!) utilizing BE1. Way back in the day, BEX used to fly to JFK and BOS using SF3. What well-heeled business traveler wants to fly on a BE1 or SF3 though? I think if advertised right, a F100 might do well to ORD two times a day by AA, or a CRJ to ATL by DL. Just an idea
