Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4694, 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 4694 earns an A+. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs close to two hours. That rests on 363 flights, with a median arrival 17 minutes early.
Set against the rest of the country, OO 4694's record is 8 points better than the US average of 77.6%. That gap is worth roughly 81 fewer late arrivals for every thousand flights.

These figures cover 363 flights between July 2025 and June 2026. The median arrival is 17 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 4694 flies
OO 4694 flies BIS to DEN without a single fixed slot. Its most common scheduled departure was 13:45, used on 73 of 363 flights, with 13:55 (57 flights) and 14:00 (49 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 13:45 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 4694 runs 7 points better at 85.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Delay causes
Why OO 4694 runs late
One category carries most of the weight here. Carrier accounts for 58% of the 5,989 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.
- 58%Carrier
- 26%Late-arriving aircraft
- 10%National Airspace System
- 7%Extreme weather
The largest share of delay minutes, 58%, 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 3,461 of the 5,989 delay minutes reported here. The split is drawn from 5,989 delay minutes reported on OO 4694.
Cancellations are rare at 0.83%, below the national 1.81% 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
7.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last close to two hours, which a normal layover absorbs.
The 516 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on two other city pairs in the data, including ORD to PSP (1) and ORD to PIA (1), but none flew often enough under OO 4694 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BIS to DEN only.
One caution: this is a thin sample. 363 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 4694
For a booking, OO 4694 has one of the better records a US domestic flight can show: 85.7% on time and 0.83% cancelled. That is a base rate, not a promise about any single day.
