I used to fly Midwest when they at least offered a "pay for your meal" service and they served warm chocolate chip cookies. My last flight to Boston had NO meals, NO cookies and the flight attendants looked like they would rather be anywhere else than on my flight.
The good old days of excellent Midwest service are gone. Welcome to Milwaukee, Southwest. I'm sure you'll be seeing a lot more of me in the future!
Cons: Indifferent flight attendants, small plane, no meal service
