What delays out of MLU were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 762 flights that departed MLU and ran 15 minutes late or more, the delay minutes break down with 41.1% put down to airline operations and 35.6% to late-arriving aircraft.
- Late-arriving aircraft 35.6%
- Airline operations 41.1%
- Air traffic & airport volume 15.3%
- Severe weather 7.8%
- 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.
