Share of 353 completed flights by arrival against schedule.
A late pushback is often recovered here: of 87 departures that left 15 minutes late or more, 28 still arrived on time. In the other direction, 24 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SAN.

Delay causes
Why UA 1626 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,147 reported delay minutes.
- 39%Late-arriving aircraft
- 30%National Airspace System
- 29%Carrier
- 2%Extreme weather
39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,147 reported delay minutes here, that single category outweighs weather by 23 to one. The split is drawn from 5,147 delay minutes reported on UA 1626.
Cancellations sit at 1.92% against a national 1.89%, which is ordinary. Diversions add another 1.37%.
Connections and routes
What a delay on this flight costs
8.2% 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.
At 2,425 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on five other city pairs in the data, including FLL to EWR (35), PBI to EWR (23) and RSW to EWR (21), but none flew often enough under UA 1626 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to SAN only.
One caution: this is a thin sample. 365 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
