Delay causes
Why F9 1268 runs late

- 71%Late-arriving aircraft
- 15%Carrier
- 14%National Airspace System
- 1%Extreme weather
71% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,733 reported delay minutes here, that single category outweighs weather by 71 to one. The split is drawn from 2,733 delay minutes reported on F9 1268.
Cancellations sit at 1.95% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
6.0% 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 about an hour, which a normal layover absorbs.
The 590 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 256 flights under F9 1268 in the data flew LAX to SLC. 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. 256 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.
