UA 1875 lands a B, level with the national rate of 77.6%. Roughly one flight in four arrives 15 minutes late or worse, and those flights are late by roughly 55 minutes on average. That is a workable record, not a spotless one. That rests on 323 flights, with a median arrival right on schedule.

These figures cover 323 flights between July 2025 and June 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.
Schedule
When UA 1875 flies
UA 1875 flies EWR to ORD without a single fixed slot. Its most common scheduled departure was 11:30, used on 94 of 323 flights, with 11:32 (70 flights) and 11:37 (63 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 11:30 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 1875 runs level with that at 77.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

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 81 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 ranged from 73.9% on Sunday to 83.0% on Monday. With about 46 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why UA 1875 runs late
One category carries most of the weight here. National Airspace System accounts for 57% of the 3,790 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.
- 57%National Airspace System
- 29%Late-arriving aircraft
- 14%Carrier
- 1%Extreme weather
57% 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 2,152 minutes out of 3,790, against a national NAS share of 21%. The split is drawn from 3,790 delay minutes reported on UA 1875.
Cancellations sit at 1.24% against a national 1.81%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
5.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last roughly 55 minutes, 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on nine other city pairs in the data, including ORD to LAS (195), 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. 323 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.
