It is a bit of a shock to see ATW go, the cost of flying out of there (on most any airline) has what has felt to be the highest. Although it never made sense to go to ATW to fly to MKE since it is less than a 2 hour drive down 41. (Then again it doesn't make much sense for UA or AA to fly MKE-ORD, but they seem to make it work... sorta)
