What delays out of LAR were put down to
Airlines file a reason with every arrival running 15 minutes late or more. Across 408 flights that departed LAR and ran 15 minutes late or more, the delay minutes break down with 32.8% put down to airline operations and 30.6% to late-arriving aircraft.
- Late-arriving aircraft 30.6%
- Airline operations 32.8%
- Air traffic & airport volume 25.2%
- Severe weather 11.4%
- Security 0%
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.
