These figures cover 314 flights between July 2025 and June 2026. The median arrival is 23 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 2743 flies
UA 2743 flies LAX to EWR without a single fixed slot. Its most common scheduled departure was 07:00, used on 145 of 314 flights, with 07:30 (100 flights) and 07:15 (53 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and UA 2743 runs 4 points better at 93.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
UA 2743 quarter by quarter
Quarter by quarter UA 2743 held fairly steady: 90.0% in Jul–Sep 2025, 93.3% in Oct–Dec 2025, 91.9% in Jan–Mar 2026 and 96.7% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, UA 2743 did best on Wednesday at 100.0% on time and worst on Saturday at 86.4%. Each day rests on about 45 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 2743 runs late
One category carries most of the weight here. Carrier accounts for 53% of the 3,180 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.
- 53%Carrier
- 28%National Airspace System
- 19%Late-arriving aircraft
The largest share of delay minutes, 53%, 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 1,688 of the 3,180 delay minutes reported here. The split is drawn from 3,180 delay minutes reported on UA 2743.
Cancellations sit at 2.23% against a national 1.81%, which is ordinary. Diversions add another 0.32%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.3% land an hour or more behind schedule, against 8.1% 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 2,454 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 two other city pairs in the data, including EWR to TPA (24) and EWR to ATL (20), but none flew often enough under UA 2743 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LAX to EWR only.
One caution: this is a thin sample. 314 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 2743
