Nah.... When AS gets rid of the -700's, there's going to be nothing under about 180 seats. No 737 will be able to make a profit hauling people with the load factors they'll get. (An AS CA already told us the loads suck a lot of the time on the larger 737's, since the -200's left.)
I'd expect the Q400's will start getting more routes as the -700's freighters carry the profitable stuff, (the mail & cargo).
Think of what happened when we went from the -200's to -400's in WA/OR/ID.
