OO 4704 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.6%.

These figures cover 345 flights between July 2025 and June 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.

Schedule

OO 4704 flies DEN to GJT without a single fixed slot. Its most common scheduled departure was 09:35, used on 157 of 345 flights, with 09:40 (74 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 09:35 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 4704 runs 3 points better at 87.0%. 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

OO 4704 quarter by quarter

OO 4704 did not run the same all year. Its best quarter was Oct–Dec 2025 at 93.1% on time and its weakest Apr–Jun 2026 at 81.0%, a swing of 12 points on roughly 86 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.

By weekday, OO 4704 did best on Saturday at 93.0% on time and worst on Wednesday at 80.0%. Each day rests on about 49 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 4704 runs late

One category carries most of the weight here. Carrier accounts for 44% of the 2,061 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.

The largest share of delay minutes, 44%, 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 906 of the 2,061 delay minutes reported here. The split is drawn from 2,061 delay minutes reported on OO 4704.

Cancellations sit at 2.03% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.0% 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 same number turns up on three other city pairs in the data, including LAX to SBA (12), DEN to CHA (3) and BOI to DEN (1), but none flew often enough under OO 4704 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to GJT only.

One caution: this is a thin sample. 345 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.
