What delays out of BGR were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 2,603 flights that departed BGR and ran 15 minutes late or more, the delay minutes break down with 38.7% put down to late-arriving aircraft and 28.7% to air traffic & airport volume.

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.
