What delays out of OGG were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 10,963 flights that departed OGG and ran 15 minutes late or more, the delay minutes break down with 47.6% put down to late-arriving aircraft and 39.6% to airline operations.

Late-arriving aircraft is the knock-on category: the plane came in late, so it went out late again. It is why a 7am problem in Newark is still a problem in Denver at dinnertime, and why it is usually the biggest slice on the bar.
