When it became clear yesterday that my destination in Northern Wisconsin was going to be snowed in, I called the Midwest airlines 800 number to request a rebooking. The Midwest agent was unfailingly polite, however I had to do a bit of pleading to get her to make the change. Basically, I had to read the National Weather Service report to her, TRUE
Checked last night and the flight that I was on was canceled, which meant that had I started out I would have been stranded in MKE at my expense.
Midwest needs to be more proactive and implement a Winter Weather waiver early in the planning process (a la Northwest). Customer's should not have to call and have requests for rebooking bucked up the chain.
Ultimately, I worked it out, but only because I was persistent.
