Historical statistics for July 2025 to June 2026, not live status. For today’s UA 1700, check with United Airlines.
UA 1700 lands a B, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 272 flights, with a median arrival 16 minutes early.
Set against the rest of the country, UA 1700's record is 5 points better than the US average of 77.6%. That gap is worth roughly 45 fewer late arrivals for every thousand flights.

These figures cover 272 flights between July 2025 and June 2026. Beyond the headline rate, 9.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Schedule
When UA 1700 flies
UA 1700 is scheduled to leave Los Angeles (LAX) at 16:30 local time and reach Newark (EWR) at 00:58. That slot held for 268 of the 272 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 16:30 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and UA 1700 runs 10 points better at 82.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
UA 1700 quarter by quarter
UA 1700 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.4% on time and its weakest Jul–Sep 2025 at 72.0%, a swing of 19 points on roughly 68 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.

By weekday, UA 1700 did best on Tuesday at 89.5% on time and worst on Thursday at 75.6%. Each day rests on about 39 flights, so a gap of 14 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 1700 runs late
One category carries most of the weight here. Late-arriving aircraft accounts for 53% of the 3,564 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%Late-arriving aircraft
- 31%Carrier
- 17%National Airspace System
53% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 3,564 reported delay minutes here, that single category outweighs weather by 53 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 3,564 delay minutes reported on UA 1700.
Cancellations sit at 1.84% against a national 1.81%, which is ordinary. Diversions add another 1.47%.
Connections and routes
What a delay on this flight costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 9.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
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 one other city pair in the data, including ORF to ORD (37), but none flew often enough under UA 1700 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. 272 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 1700
