Yup -- I used later July for the summer peak to include Delta's JFK and LGA flights, but not include the AirTran/Southwest cuts planned with the August 10th change. I'd guess that FL+WN could top 50% in June prior to the Delta LGA addition, but may slide somewhat below 50% after that 8/10 schedule goes from 58 to 50 combined FL+WN flights. Most other MKE airlines don't have seasonal adjustments of that magnitude come fall. But while the WN/FL schedule is probably set for early fall, other airlines at MKE (including F9 of course) don't lock in their schedule that far out, so there's plenty of latitude for DL, F9, UA, US and AA to make Milwaukee changes up or down for fall.
