Delay causes
What held LAS up in November
Late-arriving aircraft accounts for 44% of the 170,000 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Late-arriving aircraft
- 28%Carrier
- 27%National Airspace System
- 1%Extreme weather
- 0%Security
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 170,000 reported delay minutes here, that single category outweighs weather by 37 to one. The split is drawn from 170,205 reported delay minutes.
Cancellations sit at 1.73% against a national 2.49%, which is ordinary. Diversions add another 0.15%.
6.2% of arrivals land an hour or more late, close to the national 7.8%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
