Schedule

When OO 5952 flies

OO 5952 flies DRO to DEN without a single fixed slot. Its most common scheduled departure was 15:23, used on 117 of 364 flights, with 15:18 (52 flights) and 15:20 (49 flights) next.

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

A 15:23 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and OO 5952 runs level with that at 72.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5952 quarter by quarter

OO 5952 did not run the same all year. Its best quarter was Oct–Dec 2025 at 81.1% on time and its weakest Jul–Sep 2025 at 53.4%, a swing of 28 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, OO 5952 did best on Sunday at 80.4% on time and worst on Thursday at 64.0%. Each day rests on about 52 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5952 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 9,505 reported delay minutes.

Late-arriving aircraft
36%
National Airspace System
34%
Extreme weather
19%
Carrier
10%

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 3.1 times the usual weather exposure. The split is drawn from 9,505 delay minutes reported on OO 5952.

Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 0.27%.

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. 16.7% 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.

Every one of the 364 flights under OO 5952 in the data flew DRO to DEN. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 364 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 5952

For a booking, OO 5952 is a flight to put a long connection behind. 16.7% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
