Yes, impressive. However, take the functional meaning of the cancellation percentage with a grain of salt. For example, I was booked on a short Delta mainline flight that apparently developed a mechanical issue and that initially was pushed back from a 6:30 am departure to a 2 pm departure. It eventually left at 7:30 pm, so with a 13 h delay. They might as well have cancelled it as people were rebooked on other flights that left earlier.
