I have tried the Midwest number all day to reschedule an mke-las flight Dec 19-21. After not getting through, I went to Mitchell Airport to reschedule face to face. They seemed hesitant to help me and wanted to call the reservations number. After talking to thr agent, she looked up my flight. Midwest changed me from a 9:30 am flight to 7:30 am flight BUT they cannot confirm these changes. They told me I am on the flights but not confirmed. When I asked when I would be confirmed they said they were unsure??
