These figures cover 308 flights between September 2025 and August 2026. The median arrival is 8 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.

A 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and UA 454 runs level with that at 84.7%. 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
Quarter by quarter UA 454 held fairly steady: 78.8% in Oct–Dec 2025, 86.5% in Jan–Mar 2026, 83.0% in Apr–Jun 2026 and 85.5% in Jul–Sep 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Jan–Mar 202681 flights86.5%

By weekday, UA 454 did best on Wednesday at 91.3% on time and worst on Thursday at 76.7%. Each day rests on about 44 flights, so a gap of 15 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late UA 454 runs when it is late
UA 454 often beats the schedule: 108 of 300 completed flights, 36%, arrived 15 minutes or more early. The 46 late arrivals split 11 under half an hour, 22 between 30 and 60 minutes, and 13 an hour or more.

Share of 300 completed flights by arrival against schedule.
9 of 34 late departures made up the time and arrived on time, 26% of them. In the other direction, 21 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 DFW.
The worst days
Worst days for UA 454
The latest arrival of the period was on 18 July 2026, 6 hours 59 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The five worst days are spread across July, January, December, November and March, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 18 July 2026 | 6 hours 59 minutes | Carrier |
| 17 January 2026 | 3 hours 22 minutes | Late-arriving aircraft |
| 14 December 2025 | 3 hours 10 minutes | Extreme weather |
| 9 November 2025 | 2 hours 33 minutes | National Airspace System |
| 23 March 2026 | 1 hour 38 minutes | Late-arriving aircraft |
Delay causes
Why UA 454 runs late
National Airspace System accounts for 45% of the 2,770 delay minutes carriers reported here, and the remaining four split what is left.
- 45%National Airspace System
- 31%Carrier
- 18%Late-arriving aircraft
- 6%Extreme weather
45% 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 1,239 minutes out of 2,770, against a national NAS share of 21%. The split is drawn from 2,770 delay minutes reported on UA 454.
Cancellations sit at 1.95% against a national 1.89%, which is ordinary. Diversions add another 0.65%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.3% land an hour or more behind schedule, against 8.3% 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.
The same number turns up on eight other city pairs in the data, including DFW to SFO (40), BWI to LAX (31) and OGG to SFO (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. 308 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 84.7% on time with 1.95% cancelled over 308 flights. Those are rates from the past twelve months, not a forecast for any particular day.
