Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5772, 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 5772 lands a B−, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by close to two hours on average. That is a workable record, not a spotless one. That rests on 299 flights, with a median arrival 8 minutes early.

These figures cover 299 flights between July 2025 and June 2026. Beyond the headline rate, 10.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When OO 5772 flies

OO 5772 flies ASE to DEN without a single fixed slot. Its most common scheduled departure was 11:32, used on 108 of 299 flights, with 11:15 (49 flights) and 11:36 (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 11:32 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5772 runs level with that at 78.2%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5772 quarter by quarter

By weekday, OO 5772 did best on Thursday at 85.7% on time and worst on Monday at 69.0%. Each day rests on about 43 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5772 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 6,830 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.

49%
Extreme weather
20%
National Airspace System

Carrier
13%

Extreme weather accounts for 20% 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 3.3 times the usual weather exposure. The split is drawn from 6,830 delay minutes reported on OO 5772.

Cancellations run at 3.01%, against 1.81% nationally. That is roughly one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.4% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The same number turns up on two other city pairs in the data, including ORD to CID (13) and ORD to GRR (2), but none flew often enough under OO 5772 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ASE to DEN only.

One caution: this is a thin sample. 299 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 5772

For a booking, the cancellation rate is the figure to plan around on OO 5772: 3.01% of its 299 scheduled flights did not operate. A late arrival costs close to two hours, but a cancellation costs the day, so leave a later option open.
