IAD-LGB. Ok, LGB is their west coast ''focus city''. IAD-OAK. Ok, take on a major where the fares are high (into SFO). IAD-FLL. Leisure route that is underserved. So can we expect more of this from B6, such as IAD-DEN (not even flown by Frontier) or IAD-TPA? Or does WN''s BWI hub make expanding in the Washington area not as lucrative as expanding elsewhere?
