As for the link to Flight aware, one of the tricky things is people in this thread consider regionals to be Delta, and flightaware does not. But yesterday, AA delayed 25% of flights and canceled 2%. Delta delayed 12% and canceled 8%. United delayed 21% and canceled 3%. I don't think a pattern like this shows what you think.
