Depends on where you live. MHT, PVD, and ORF have Southwest flights, so that's nice. If you're from the East Coast, Colgan does a lot of flying into PIT and LGA, where you could grab a lot of US Air/US Air Express stuff. Now we're doing United Express flying into Dulles, but AVOID IAD LIKE THE PLAGUE. Hope that helps, PM me if you'd like.
