We have flown with ATA numerious times over the past 8 or so years and have never had one problem with them yet. I prefer to fly out of O'hare as it is closer to my home, but if ATA has the best deal I will not hesitate to use them. They have a newer fleet of planes now and their flight schedules aren't too bad. They are pretty comparable to the other majors, except they don't have a first class section.
