Nothing else seems notable, although you can't really know for sure until the Southwest schedule comes out too. Then I'll do a year-over-year check to see if anything is different.
Here's how the
year-over-year FL+WN changes appear versus last October for Milwaukee:
increases YOY
+2 MSP
+1 DEN
+1 BOS
+1 PHX
decreases YOY
-2 DSM
-2 CAK
-1 BWI
-1 MCO
-1 LAS
-1 TPA
-1 MSY
Note that this is year-over-year change, so some of these increses or cuts are not "new" with the October schedule. For example, the 3rd MKE-DEN flight was added in early 2012 and still shows as a year-over-year increase; it is not a new flight starting with this schedule.
The only notable "new" things IMHO for Milwaukee in the October schedule are:
MKE-MSP goes from 4x to 5x
MKE-BOS, which loses the 4th frequency after 8/10, gets it back as of 9/29
MKE-DSM ends, moving to MDW-DSM
Milwaukee-Florida flying which sometimes ramps up in October does not appear to be doing so quite yet.
