These figures cover 365 flights between September 2025 and August 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.

The latest arrival of the period was on 2 February 2026, 6 hours 5 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 February 2026 | 6 hours 5 minutes | Carrier |
| 8 September 2025 | 5 hours 25 minutes | Carrier |

Delay causes
Why UA 2375 runs late
Carrier accounts for 86% of the 1,773 delay minutes carriers reported here, and the remaining four split what is left.
- 86%Carrier
- 14%National Airspace System
The largest share of delay minutes, 86%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,530 of the 1,773 delay minutes reported here. The split is drawn from 1,773 delay minutes reported on UA 2375.
Cancellations are rare at 0.55%, 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 1.7% 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 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.
The same number turns up on three other city pairs in the data, including DEN to TPA (180), 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: 96.7% on time and 0.55% cancelled. That is a base rate, not a promise about any single day.
