Across the year
UA 2270 quarter by quarter
UA 2270 did not run the same all year. Its best quarter was Jan–Mar 2026 at 86.5% on time and its weakest Jul–Sep 2026 at 73.8%, a swing of 13 points on roughly 85 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.

- Jan–Mar 202690 flights86.5%
- Apr–Jun 202691 flights76.9%

By weekday, UA 2270 did best on Monday at 91.9% on time and worst on Thursday at 70.3%. Each day rests on about 37 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Share of 255 completed flights by arrival against schedule.
4 of 32 late departures made up the time and arrived on time, 13% of them. In the other direction, 22 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 AUS.
The worst days
Worst days for UA 2270
The latest arrival of the period was on 17 February 2026, 4 hours 38 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 17 February 2026 | 4 hours 38 minutes | Late-arriving aircraft |
| 20 August 2026 | 3 hours 14 minutes | Late-arriving aircraft |
| 25 February 2026 | 2 hours 53 minutes | Late-arriving aircraft |
| 16 April 2026 | 2 hours 40 minutes | Late-arriving aircraft |

Delay causes
Why UA 2270 runs late
Late-arriving aircraft accounts for 42% of the 3,202 delay minutes carriers reported here, and the remaining four split what is left.
- 42%Late-arriving aircraft
- 30%Carrier
- 25%National Airspace System
- 3%Extreme weather
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,202 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 3,202 delay minutes reported on UA 2270.
Cancellations are rare at 0.39%, 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
8.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 775 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 four other city pairs in the data, including ORF to DEN (156), SAN to DEN (107) and RDU to DEN (45), but none flew often enough under UA 2270 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to AUS only.
One caution: this is a thin sample. 256 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 2270
