I agree that the midwest is lacking. I would gather that B6 has 2 options. Option one would be to pick up places like STL, MDW/ORD, MKE, MSP, MCI, HOU/IAH, and DFW, just to name a few. The other option would to be filling in the gaps withing the current structure. The service from IAD to the cities in Florida are minimal at best. They have yet to go IAD to MCO and TPA. BOS has no direct service to RDU, CLT, JAX, AUA, and SJU on the east coast and PDX, BUR, and SAN on the west coast. They really have two choice when it comes the short term. Option 1 or Option 2? I would go with Option 1 and connect BOS and IAD through JFK, then beef up everything else later.
