I've never understood the rap on AT here. I think I've had maybe one flight on a legacy carrier that WASN'T changed at least once, I've taken to checking my itinerary weekly because of that and I've always gotten the substitute flights I've wanted. As for misplaced luggage, USAir did this for one bag on the return flight one time, that's it. I have no brand loyalty, we'll probably use JetBlue in March 2011, this will be our second time with them.
