From my own experience, it's not. The cluster two weeks ago was caused by MIA, not the airline. I've flown well over a million miles since 2001 and the last three years have been the busiest for me, with 84 flights last year. I can count on one hand the flight delays I've had of more than one hour last year. That's playing the averages, though. If you do one round trip per year and one flight is delayed, that's 50% and a horrible average. Worse if it's both flights. 3 delays in 84 flights is 3.5%. I lost more time through the damn I-294 construction traffic.Becoming all too common
Still, like everyone else, I hate flight delays.
