Will CAK really be the winner?
The LCC's (FL, F9) went to CAK because if they would fly out of CLE then CO would eat them alive. Look at what happenned to FL at the begining of this decade fighting with US at PIT...they had to pull out of many routes like PIT-LGA because of the fierce competition. (although I did like the $29 flights!)

Instead they went to CAK, and CO actually did match their fares for a few years to a T, but eventually CO stopped trying to match FL's fares.

If CoUniHound shuts down the CLE hub I'd expect some airlines to possibly even move from CAK to CLE which is more centrally located than CAK.

FL even flies to FNT and DTW, I wouldn't be surprised if they started flying from both airports for a period to see which does better.

If not that I'd expect B6 to fly CLE-JFK and CLE-BOS.
