Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5701, 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 5701 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 13 points better than the national rate of 77.6%.

These figures cover 337 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 OO 5701 flies

OO 5701 is scheduled to leave Sioux Falls (FSD) at 06:00 local time and reach Denver (DEN) at 07:05. That slot held for 275 of the 337 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5701 runs level with that at 90.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Delay causes

Why OO 5701 runs late

One category carries most of the weight here. Carrier accounts for 67% of the 4,439 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
67%
Extreme weather
29%
National Airspace System
4%
Late-arriving aircraft
1%

Extreme weather accounts for 29% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 4.6 times the usual weather exposure. The split is drawn from 4,439 delay minutes reported on OO 5701.

Cancellations sit at 2.08% 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 3.6% 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 SFO to LAX (1), but none flew often enough under OO 5701 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to FSD to DEN only.

One caution: this is a thin sample. 337 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 5701
