These figures cover 363 flights between September 2025 and August 2026. The median arrival is 22 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.

The latest arrival of the period was on 14 December 2025, 7 hours 13 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across December, October, November and September, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 14 December 2025 | 7 hours 13 minutes | Late-arriving aircraft |
| 4 October 2025 | 6 hours 25 minutes | Carrier |

Delay causes
Why UA 2743 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 2,460 reported delay minutes.
- 40%National Airspace System
- 33%Carrier
- 27%Late-arriving aircraft
40% 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 985 minutes out of 2,460, against a national NAS share of 21%. The split is drawn from 2,460 delay minutes reported on UA 2743.
Cancellations sit at 1.65% against a national 1.89%, which is ordinary. Diversions add another 1.38%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.6% 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 2,454 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. 363 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
