Operations are MKE are a mess. I've been auto-rebooked three times, and each time the new flights have been cancelled. Lines at the ticket counter are a mess, and hold times are 2+ hours.
I have already paid for a hotel tonight at MKE, but I wonder if I just drive to ORD, that agents there could handle the rebooking.
Not sure why only DL flights are being cancelled. Other airlines appear to be running normal operations, albeit with minor delays.
I can't rebook via the app because there is no option to do so.
