Midwest Express is a "business class" airline. It was orignially the corporate airline of Kimberly-Clark (the paper/feminine hygine product company). While the drinks are free, lobster is often served and fresh-baked cookies are the norm, the entire fleet consists of ancient DC-9s and the seats are comparable to the worst seats in UA 1st class.

Back when I worked for a Wisconsin Legislator, I took the DCA-Milwaukee flight often and it was always good, but certainly never "First Class"...
