These figures cover 330 flights between September 2025 and August 2026. On-time means an arrival less than 15 minutes after the scheduled gate time, the same threshold the Department of Transportation uses in its own reports. Cancelled and diverted flights are excluded from the on-time rate and counted separately, which is why the cancellation column matters on its own.

Across the year
UA 1875 quarter by quarter
UA 1875 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.9% on time and its weakest Oct–Dec 2025 at 68.7%, a swing of 19 points on roughly 83 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 1875 did best on Saturday at 83.3% on time and worst on Sunday at 71.1%. Each day rests on about 47 flights, so a gap of 12 points is worth noticing but could still narrow in another year.

Share of 323 completed flights by arrival against schedule.
11 of 51 late departures made up the time and arrived on time, 22% of them. In the other direction, 32 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at ORD.
The worst days
Worst days for UA 1875
The latest arrival of the period was on 9 November 2025, 9 hours 52 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across November, July, March, December and August, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 9 hours 52 minutes | Late-arriving aircraft |
| 21 July 2026 | 9 hours 29 minutes | Extreme weather |
| 6 March 2026 | 3 hours 54 minutes | National Airspace System |

Delay causes
Why UA 1875 runs late
National Airspace System accounts for 48% of the 4,521 delay minutes carriers reported here, and the remaining four split what is left.
- 48%National Airspace System
- 26%Late-arriving aircraft
- 16%Extreme weather
- 9%Carrier
Extreme weather accounts for 16% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.7 times the usual weather exposure. The split is drawn from 4,521 delay minutes reported on UA 1875.
Cancellations sit at 1.82% against a national 1.89%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
6.2% of arrivals land an hour or more late, close to the national 8.3%, so 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.
The 719 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on seven other city pairs in the data, including ORD to LAS (235), RDU to EWR (36) and DEN to XNA (31), but none flew often enough under UA 1875 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to ORD only.
One caution: this is a thin sample. 330 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 1875
For a booking, read UA 1875 as 77.7% on time with 1.82% cancelled over 330 flights. Those are rates from the past twelve months, not a forecast for any particular day.
