Historical statistics for July 2025 to June 2026, not live status. For today’s UA 2856, check with United Airlines.

UA 2856 sits in the middle of the pack with a C. Close to three flights in four arrive on time by the DOT's definition, 4 points worse than the national rate of 77.6%. The late ones land a little over an hour behind schedule. That rests on 301 flights, with a median arrival 4 minutes early.

The national on-time rate over the same period is 77.6%, so UA 2856 runs 4 points behind the country as a whole. Across a thousand flights that is about 43 extra late arrivals.

These figures cover 301 flights between July 2025 and June 2026. Beyond the headline rate, 12.7% 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 2856 flies

UA 2856 flies EWR to DFW without a single fixed slot. Its most common scheduled departure was 18:29, used on 37 of 301 flights, with 19:13 (31 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 18:29 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and UA 2856 runs 5 points better at 73.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

UA 2856 next to EWR to DFW

Every carrier on EWR to DFW combined arrived on time 79.2% of the time across 3,571 flights, so UA 2856 is 6 points behind it.

Across its whole network United Airlines managed 79.0%, which this flight trails by 6 points.

Across the year

UA 2856 quarter by quarter

Quarter by quarter UA 2856 held fairly steady: 75.3% in Oct–Dec 2025, 68.7% in Jan–Mar 2026 and 73.6% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, UA 2856 did best on Wednesday at 80.5% on time and worst on Friday at 65.9%. Each day rests on about 43 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2856 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 48% of the 6,191 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.

  • Late-arriving aircraft
    48%
  • National Airspace System
    23%
  • Carrier
    21%
  • Extreme weather
    7%
  • Security
    1%

48% 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 6,191 reported delay minutes here, that single category outweighs weather by 7 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 6,191 delay minutes reported on UA 2856.

Cancellations run at 2.66%, against 1.81% nationally. That is about one flight in 40 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.7% 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.

The 1,372 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 three other city pairs in the data, including EWR to JAX (49), RDU to EWR (21) and IAH to EWR (14), but none flew often enough under UA 2856 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to DFW only.

One caution: this is a thin sample. 301 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 2856

For a booking, the cancellation rate is the figure to plan around on UA 2856: 2.66% of its 301 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.
