Across the year
UA 407 quarter by quarter
UA 407 did not run the same all year. Its best quarter was Oct–Dec 2025 at 72.2% on time and its weakest Jul–Sep 2026 at 44.6%, a swing of 28 points on roughly 91 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 407 did best on Tuesday at 80.6% on time and worst on Wednesday at 60.5%. Each day rests on about 39 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Share of 265 completed flights by arrival against schedule.
13 of 68 late departures made up the time and arrived on time, 19% of them. In the other direction, 32 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 DEN.
The worst days
Worst days for UA 407
The latest arrival of the period was on 11 March 2026, 6 hours 41 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. On three of the five worst days the largest share was filed as a late-arriving aircraft.

|---|---|---|
| 11 March 2026 | 6 hours 41 minutes | National Airspace System |
| 20 August 2026 | 6 hours 8 minutes | Late-arriving aircraft |
| 8 November 2025 | 5 hours 46 minutes | Late-arriving aircraft |

Delay causes
Why UA 407 runs late
Late-arriving aircraft accounts for 47% of the 6,920 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 36%National Airspace System
- 13%Carrier
- 4%Extreme weather
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,920 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 6,920 delay minutes reported on UA 407.
Cancellations run at 3.28%, 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
13.6% 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.
At 1,605 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
The same number turns up on four other city pairs in the data, including DEN to GJT (32), ORD to TVC (25) and DEN to FAR (21), but none flew often enough under UA 407 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to DEN only.
One caution: this is a thin sample. 274 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 407
For a booking, the cancellation rate is the figure to plan around on UA 407: 3.28% of its 274 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.
