I believe this expansion out of Milwaukee is not about Midwest but AirTran establishing a good base for its east-west network. Before ATA went into Ch. 11, they had good loads from BOS, LGA, DCA connecting through Midway to SEA, SFO, LAX, PHX, and LAS. But ATA was using larger aircraft (757 and 737-800) and AirTran will be flying the same routes with smaller 737-700 aircraft. Why MKE and not MDW? I believe not having to go head to head with Southwest was a big factor. The only aircraft at the moment that can compete with AirTran on those west coast routes out of Milwaukee are Midwest MD-80s. The head to head competition between the MD-80 and 737-700 at high energy prices, well the 737-700 will win everytime. AirTran is testing these new markets during the busy summer season. If they do well, the routes will become year round. More cities will be added...DFW, DEN, PHL, and probable DCA or IAD. You may even see the launch of Salt Lake city as well. AirTran will attempt to maximize the use of the gates they have in Milwaukee. More JOBS for Milwaukee to come via AirTran.
