What delays out of EUG were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 3,989 flights that departed EUG and ran 15 minutes late or more, the delay minutes break down with 43.2% put down to airline operations and 31% to late-arriving aircraft.
- Late-arriving aircraft 31%
- Airline operations 43.2%
- Air traffic & airport volume 18.9%
- Severe weather 6.7%
- Security 0.1%
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.
