UA 2679 lands a B, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 315 flights, with a median arrival 4 minutes early.

These figures cover 315 flights between July 2025 and June 2026. The median arrival is 4 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 2679 flies

UA 2679 flies EWR to LAX without a single fixed slot. Its most common scheduled departure was 10:00, used on 180 of 315 flights, with 10:30 (77 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 10:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 2679 runs 6 points worse at 77.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Against the route

UA 2679 next to EWR to LAX

Every carrier on EWR to LAX combined arrived on time 71.9% of the time across 4,927 flights, so UA 2679 is 6 points ahead of it. United flew 3,540 flights on the same city pair under all its flight numbers, including this one, and those ran 72.2% on time. Across its whole network United Airlines managed 79.0%, close to this flight's figure.

Across the year

UA 2679 quarter by quarter

UA 2679 did not run the same all year. Its best quarter was Jul–Sep 2025 at 85.7% on time and its weakest Oct–Dec 2025 at 67.8%, a swing of 18 points on roughly 79 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Jan–Mar 202690 flights81.4%

Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, UA 2679 did best on Wednesday at 86.7% on time and worst on Friday at 68.9%. Each day rests on about 45 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2679 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 4,560 reported delay minutes.

Carrier
40%
Late-arriving aircraft
34%
National Airspace System
25%
Extreme weather
1%

The largest share of delay minutes, 40%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,814 of the 4,560 delay minutes reported here. The split is drawn from 4,560 delay minutes reported on UA 2679.

Cancellations sit at 1.59% against a national 1.81%, which is ordinary. Diversions add another 0.32%.

Connections and routes

What a delay on this flight costs

7.8% 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 2,454 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 six other city pairs in the data, including LAX to LAS (89), DEN to PHL (31) and DEN to MTJ (18), but none flew often enough under UA 2679 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to LAX only.

One caution: this is a thin sample. 315 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.
