These figures cover 346 flights between July 2025 and June 2026. The median arrival is 11 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.
Schedule
When UA 1826 flies
UA 1826 flies EWR to SAN without a single fixed slot. Its most common scheduled departure was 09:15, used on 37 of 346 flights, with 06:55 (37 flights) and 16:59 (35 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 09:15 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 1826 runs level with that at 84.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

By weekday, UA 1826 did best on Friday at 89.6% on time and worst on Sunday at 72.9%. Each day rests on about 49 flights, so a gap of 17 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1826 runs late
One category carries most of the weight here. National Airspace System accounts for 47% of the 3,408 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 47%National Airspace System
- 23%Late-arriving aircraft
- 23%Carrier
- 7%Extreme weather
47% 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 1,610 minutes out of 3,408, against a national NAS share of 21%. The split is drawn from 3,408 delay minutes reported on UA 1826.
Cancellations sit at 1.16% against a national 1.81%, which is ordinary. Diversions add another 0.58%.
Connections and routes
What a delay on this flight costs
5.3% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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 two other city pairs in the data, including ATL to EWR (29) and EWR to SAT (18), 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. 346 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.
