UA 2307 lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 365 flights, with a median arrival 8 minutes early.

Set against the rest of the country, UA 2307's record is 6 points better than the US average of 77.6%. That gap is worth roughly 62 fewer late arrivals for every thousand flights.

These figures cover 365 flights between July 2025 and June 2026. The median arrival is 8 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 2307 flies

UA 2307 flies DEN to LIH without a single fixed slot. Its most common scheduled departure was 12:00, used on 211 of 365 flights, with 12:05 (154 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 12:00 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and UA 2307 runs 5 points better at 83.8%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

UA 2307 quarter by quarter

Quarter by quarter UA 2307 held fairly steady: 82.8% in Jul–Sep 2025, 87.0% in Oct–Dec 2025, 82.8% in Jan–Mar 2026 and 82.4% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202592 flights82.8%
Oct–Dec 202592 flights87.0%
Jan–Mar 202690 flights82.8%
Apr–Jun 202691 flights82.4%

Scale runs 75% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, UA 2307 did best on Thursday at 90.0% on time and worst on Sunday at 75.0%. Each day rests on about 52 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why UA 2307 runs late

One category carries most of the weight here. Carrier accounts for 53% of the 3,669 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.

Carrier
53%
Late-arriving aircraft
32%
National Airspace System
14%

The largest share of delay minutes, 53%, 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 1,956 of the 3,669 delay minutes reported here. The split is drawn from 3,669 delay minutes reported on UA 2307.

Cancellations sit at 1.64% against a national 1.81%, which is ordinary. Diversions add another 0.55%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.8% 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.

At 3,414 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 IAH to DEN (36), OKC to DEN (35) and MEM to DEN (20), but none flew often enough under UA 2307 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to LIH 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.
