Historical statistics for September 2025 to August 2026, not live status. For today’s UA 254, check with United Airlines.

UA 254 earns an F−, which is as low as this site's scale goes for a reason. Only 43.5% of flights arrive inside the 15-minute window, 34 points worse than the national rate of 77.3%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 306 flights, with a median arrival 18 minutes late.

The national on-time rate over the same period is 77.3%, so UA 254 runs 34 points behind the country as a whole. Across a thousand flights that is about 338 extra late arrivals.

Across the year

UA 254 quarter by quarter

UA 254 did not run the same all year. Its best quarter was Apr–Jun 2026 at 51.1% on time and its weakest Oct–Dec 2025 at 31.7%, a swing of 19 points on roughly 77 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.

  • Oct–Dec 202565 flights31.7%
  • Jan–Mar 202689 flights47.1%
  • Apr–Jun 202691 flights51.1%
  • Jul–Sep 202661 flights39.7%

Scale runs 25% to 55%.

By weekday, UA 254 did best on Tuesday at 52.4% on time and worst on Thursday at 34.2%. Each day rests on about 44 flights, so a gap of 18 points is worth noticing but could still narrow in another year.

Share of 294 completed flights by arrival against schedule.

Time lost at the gate mostly stays lost. Of 94 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 79 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.

Delay causes

Why UA 254 runs late

National Airspace System accounts for 54% of the 13,000 delay minutes carriers reported here, and the remaining four split what is left.

  • National Airspace System
    54%
  • Late-arriving aircraft
    31%
  • Carrier
    13%
  • Extreme weather
    3%

54% 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 6,861 minutes out of 13,000, against a national NAS share of 21%. The split is drawn from 12,808 delay minutes reported on UA 254.

Cancellations run at 3.59%, against 1.89% nationally. That is about one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

22.1% 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.

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 nine other city pairs in the data, including SAT to EWR (93), BDL to IAD (23) and MCO to EWR (21), but none flew often enough under UA 254 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. 306 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 254

For a booking, the cancellation rate is the figure to plan around on UA 254: 3.59% of its 306 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
