It was Air Tran. And the lame excuse was a ramp problem. Too many Aircraft coming into Atlanta at the same time of the morning.
What a crock. That seems like something that should be fairly obvious when they are coordinating flight schedules. It's not like these flights are scheduled the day before. I always fly out of Toronto or Buffalo and have never had a flight cancelled, although there have been weather delays out of Buffalo.
Do you suspect some other underlying economic reason?
