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 2026 at 69.0%, a swing of 22 points on roughly 66 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.

Delay causes
Why UA 1700 runs late
Late-arriving aircraft accounts for 54% of the 3,562 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 31%Carrier
- 15%National Airspace System
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,562 reported delay minutes here, that single category outweighs weather by 54 to one. The split is drawn from 3,562 delay minutes reported on UA 1700.
Cancellations sit at 1.52% against a national 1.89%, which is ordinary. Diversions add another 1.52%.
Connections and routes
What a delay on this flight costs
9.8% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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. 263 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
For a booking, read UA 1700 as 81.6% on time with 1.52% cancelled over 263 flights. Those are rates from the past twelve months, not a forecast for any particular day.
