Actually Midway Airlines was flying it even way before you guys. Many of our ex-Midway pilots have told me it was their best money making route. We shouldn't have waited this long.
Then ATA flew those routes. I personally never carried less than 150 pax out of MSP on the -800 and that was with ATA's near non-existant marketing. All I ever heard from the MSP pax was how glad they were we flew in there so they would not have to fly NWA.
