Historical statistics for July 2025 to June 2026, not live status. For today’s UA 454, check with United Airlines.
UA 454 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 259 flights, with a median arrival 7 minutes early.
Set against the rest of the country, UA 454's record is 8 points better than the US average of 77.6%. That gap is worth roughly 75 fewer late arrivals for every thousand flights.

These figures cover 259 flights between July 2025 and June 2026. The median arrival is 7 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.
Schedule
When UA 454 flies
UA 454 flies EWR to DFW without a single fixed slot. Its most common scheduled departure was 09:00, used on 132 of 259 flights, with 09:06 (41 flights) and 09:31 (31 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 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 454 runs level with that at 85.1%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year
UA 454 quarter by quarter
UA 454 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.1% on time and its weakest Oct–Dec 2025 at 78.8%, a swing of 18 points on roughly 65 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.
- Jul–Sep 202537 flights97.1%
- Oct–Dec 202552 flights78.8%
- Jan–Mar 202681 flights86.5%
- Apr–Jun 202689 flights83.0%
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 454 did best on Wednesday at 94.7% on time and worst on Monday at 75.0%. Each day rests on about 37 flights, so a gap of 20 points is worth noticing but could still narrow in another year.
Delay causes
Why UA 454 runs late
One category carries most of the weight here. National Airspace System accounts for 53% of the 2,061 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.

- 20%Late-arriving aircraft
- 20%Carrier
- 8%Extreme weather
53% 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 1,085 minutes out of 2,061, against a national NAS share of 21%. The split is drawn from 2,061 delay minutes reported on UA 454.
Cancellations sit at 2.32% against a national 1.81%, which is ordinary. Diversions add another 1.54%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.4% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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 ten other city pairs in the data, including IAD to DEN (48), BWI to LAX (31) and SFO to IAD (19), but none flew often enough under UA 454 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. 259 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 454
For a booking, read UA 454 as 85.1% on time with 2.32% cancelled over 259 flights. Those are rates from the past twelve months, not a forecast for any particular day.
