What delays out of BRO were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 812 flights that departed BRO and ran 15 minutes late or more, the delay minutes break down with 34.9% put down to late-arriving aircraft and 34.2% to airline operations.
- Late-arriving aircraft 34.9%
- Airline operations 34.2%
- Air traffic & airport volume 14.6%
- Severe weather 16%
- Security 0.3%
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.
