Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5730, check with SkyWest Airlines. SkyWest Airlines flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

OO 5730 earns an A. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 16 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 45 minutes. That rests on 322 flights, with a median arrival 12 minutes early.

These figures cover 322 flights between July 2025 and June 2026. The median arrival is 12 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 OO 5730 flies

OO 5730 flies DEN to JAC without a single fixed slot. Its most common scheduled departure was 08:00, used on 236 of 322 flights, with 08:01 (49 flights) and 08:05 (37 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 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and OO 5730 runs 9 points better at 93.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

By weekday, OO 5730 ranged from 89.1% on Sunday to 97.8% on Tuesday. With about 46 flights behind each day, a spread of 9 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why OO 5730 runs late

One category carries most of the weight here. Carrier accounts for 70% of the 882 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
70%
National Airspace System
21%
Late-arriving aircraft
9%

The largest share of delay minutes, 70%, 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 616 of the 882 delay minutes reported here. The split is drawn from 882 delay minutes reported on OO 5730.

Cancellations sit at 2.17% against a national 1.81%, which is ordinary. Diversions add another 1.55%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 1.3% 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 one other city pair in the data, including SLC to JAC (1), but none flew often enough under OO 5730 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to JAC only.

One caution: this is a thin sample. 322 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 OO 5730
