These figures cover 364 flights between September 2025 and August 2026. The median arrival is 9 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 09:40 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 83.9%, and UA 1010 runs 4 points better at 87.5%. 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 1010 quarter by quarter
UA 1010 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.7% on time and its weakest Jul–Sep 2026 at 75.4%, a swing of 21 points on roughly 73 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 202530 flights96.7%
- Oct–Dec 202592 flights91.3%
- Jan–Mar 202689 flights86.4%
- Apr–Jun 202691 flights90.0%

Scale runs 65% to 100%.
By weekday, UA 1010 did best on Wednesday at 94.1% on time and worst on Saturday at 76.5%. Each day rests on about 52 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Arrival by arrival
How late UA 1010 runs when it is late
UA 1010 often beats the schedule: 116 of 361 completed flights, 32%, arrived 15 minutes or more early. The 45 late arrivals split 17 under half an hour, 14 between 30 and 60 minutes, and 14 an hour or more.

Share of 361 completed flights by arrival against schedule.
9 of 35 late departures made up the time and arrived on time, 26% of them. In the other direction, 19 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 TPA.
The worst days
Worst days for UA 1010
The latest arrival of the period was on 21 March 2026, 5 hours 4 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across March, December, July and August, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 21 March 2026 | 5 hours 4 minutes | Late-arriving aircraft |
| 19 December 2025 | 4 hours 45 minutes | Late-arriving aircraft |
| 11 July 2026 | 3 hours 36 minutes | Carrier |
| 2 August 2026 | 2 hours 58 minutes | Carrier |
| 27 December 2025 | 2 hours 39 minutes | National Airspace System |
Delay causes
Why UA 1010 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,903 reported delay minutes.
- 36%National Airspace System
- 34%Late-arriving aircraft
- 30%Carrier
34% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,903 reported delay minutes here, that single category outweighs weather by 34 to one. The split is drawn from 2,903 delay minutes reported on UA 1010.
Cancellations are rare at 0.27%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.9% 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.
At 1,506 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 five other city pairs in the data, including TPA to ORD (155), PSP to DEN (53) and LAX to DEN (47), but none flew often enough under UA 1010 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to TPA only.
One caution: this is a thin sample. 364 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 1010
For a booking, UA 1010 has one of the better records a US domestic flight can show: 87.5% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
