These figures cover 365 flights between July 2025 and June 2026. The median arrival is 14 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 2375 flies
UA 2375 flies PDX to DEN without a single fixed slot. Its most common scheduled departure was 08:30, used on 135 of 365 flights, with 08:50 (90 flights) and 08:35 (68 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 08:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and UA 2375 runs 12 points better at 96.4%. 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 2375 quarter by quarter
Quarter by quarter UA 2375 held fairly steady: 94.5% in Jul–Sep 2025, 95.7% in Oct–Dec 2025, 96.6% in Jan–Mar 2026 and 98.9% in Apr–Jun 2026. A spread of 4 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

- Oct–Dec 202592 flights95.7%
- Jan–Mar 202690 flights96.6%
- Apr–Jun 202691 flights98.9%
Scale runs 85% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, UA 2375 ranged from 92.3% on Wednesday to 100.0% on Saturday. With about 52 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why UA 2375 runs late
One category carries most of the weight here. Carrier accounts for 82% of the 1,528 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.
- 82%Carrier
- 16%National Airspace System
- 2%Late-arriving aircraft
The largest share of delay minutes, 82%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 1,255 of the 1,528 delay minutes reported here. The split is drawn from 1,528 delay minutes reported on UA 2375.
Cancellations are rare at 0.55%, below the national 1.81% 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 1.4% 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 991 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 three other city pairs in the data, including DEN to TPA (118), DEN to ABQ (18) and DEN to AUS (11), but none flew often enough under UA 2375 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to PDX to DEN only.
One caution: this is a thin sample. 365 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 2375
For a booking, UA 2375 has one of the better records a US domestic flight can show: 96.4% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
