I was wondering what poll you saw rated Midway as the #1 carrier as far as customer satisfaction? I've heard many good and bad things about Midway.
I know they've recently taken a lot of steps in increasing customer satisfaction, however I would be VERY surprised to learn that they are ahead of Midwest Express, Southwest, or even Continental in that category. I checked epinons.com, and they are currently ranked #11 out of the 27 US Airlines listed which placed them ahead of United, American, and Delta.
They do have some pluses obviously including hubbing at an uncongested airport (RDU), committed to operating a young, advanced fleet (CRJs, F100s, and B737-700s), and they're one of the few startup/low fare carriers to offer a premium cabin (Carolina Class).
I've also heard a lot recently, throughout the biz, that their future is financially uncertain (anybody else shed any light on this?). Don't get me wrong, I hope they make it, they seem like a great little airline, but while their customer satisfaction may be higher than that of the big three, I hardly think they are the best in the industry.
