This isn't entirely true. They started offering two levels of service, maintaining the 2-across leather seats on their "signature service."
Unfortunately, it's inevitable that Midwest will be gobbled up by AirTran.
I'll miss Midwest. Not necessarily for the food or the seats, but for the non-stop flights. It was worth an extra 75 - 100 dollars to avoid a three-hour layover in Detroit, Newark or Minneapolis.
From what I've read Airtran plans to keep all of Midwest's routes. The main reason they want it is to have the additional routes and planes, plus Midwest's hub.
