Delay causes
Why F9 2232 runs late
Late-arriving aircraft accounts for 59% of the 4,509 delay minutes carriers reported here, and the remaining four split what is left.
- 59%Late-arriving aircraft
- 21%National Airspace System
- 19%Carrier
- 1%Extreme weather
59% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,509 reported delay minutes here, that single category outweighs weather by 50 to one. The split is drawn from 4,509 delay minutes reported on F9 2232.
Cancellations are rare at 0.69%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
6.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
Every one of the 290 flights under F9 2232 in the data flew ONT to LAS. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 290 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking F9 2232
For a booking, read F9 2232 as 79.5% on time with 0.69% cancelled over 290 flights. Those are rates from the past twelve months, not a forecast for any particular day.
