Midwest has been almost my exclusive airline of choice for about 12 years now, and I live 10 minutes from O'Hare. With the turmoil within the airline the past year or so, my past four flights (2 round-trips) have been on Airtran, (with business class upgrade) and I have been very pleased with their service, comfort, etc. There is no way today that any airline could provide the level of service for the money that Midwest had provided in the past, that's a given; it's a different world out there today. Once the dust settles and Frontier is fully incorporated into the workings there in MKE, I will again give them a try, provided they have seating comparable to Airtran business or Midwest's Signature avaialble.
