Access to previously-made reservations on the Midwest site
Reservations past 10/1 which were previously made on the Midwest site were recently locked out -- when you clicked on them you got a message that there had been a schedule change and you needed to contact a Midwest AIrlines schedule change agent. I have two such reservations, and they are both now available to view and modify.

Seat Assignments after 10/1
When these reservations were locked out, I checked seatmaps for the seats I had reserved and they were open, meaning I had lost my previously-assigned seat assignments. Those seat assignments have been restored -- I see them when I access the reservations, and the seats show as reserved on seatmaps.
