These figures cover 335 flights between July 2025 and June 2026. Beyond the headline rate, 15.9% 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 5774 flies

OO 5774 flies ASE to DEN without a single fixed slot. Its most common scheduled departure was 13:22, used on 58 of 335 flights, with 13:30 (49 flights) and 13:15 (42 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 13:22 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5774 runs 4 points worse at 75.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5774 quarter by quarter

Quarter by quarter OO 5774 held fairly steady: 70.5% in Jul–Sep 2025, 77.5% in Oct–Dec 2025, 77.4% in Jan–Mar 2026 and 75.0% in Apr–Jun 2026. A spread of 7 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jan–Mar 202690 flights77.4%

By weekday, OO 5774 did best on Wednesday at 89.1% on time and worst on Monday at 66.7%. Each day rests on about 48 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5774 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 9,609 reported delay minutes.

Late-arriving aircraft
32%
National Airspace System
30%
Carrier
19%
Extreme weather
19%

Extreme weather accounts for 19% 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 3.0 times the usual weather exposure. The split is drawn from 9,609 delay minutes reported on OO 5774.

Cancellations run at 3.88%, against 1.81% nationally. That is about one flight in 25 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. 15.9% 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 one other city pair in the data, including BDL to ORD (13), but none flew often enough under OO 5774 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. 335 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 5774

For a booking, the cancellation rate is the figure to plan around on OO 5774: 3.88% of its 335 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.
