These figures cover 365 flights between September 2025 and August 2026. The median arrival is 14 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Share of 358 completed flights by arrival against schedule.
5 of 29 late departures made up the time and arrived on time, 17% of them. In the other direction, 23 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 1826 runs late
National Airspace System accounts for 59% of the 2,378 delay minutes carriers reported here, and the remaining four split what is left.
- 59%National Airspace System
- 26%Carrier
- 14%Late-arriving aircraft
- 1%Extreme weather
59% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,397 minutes out of 2,378, against a national NAS share of 21%. The split is drawn from 2,378 delay minutes reported on UA 1826.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.55%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.5% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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 one other city pair in the data, including ATL to EWR (29), but none flew often enough under UA 1826 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
Booking UA 1826
For a booking, UA 1826 has one of the better records a US domestic flight can show: 86.9% on time and 1.37% cancelled. That is a base rate, not a promise about any single day.
