These figures cover 326 flights between July 2025 and June 2026. Beyond the headline rate, 13.0% 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 5886 flies

OO 5886 flies DEN to SGF without a single fixed slot. Its most common scheduled departure was 17:25, used on 69 of 326 flights, with 17:20 (49 flights) and 17:38 (36 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 17:25 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and OO 5886 runs level with that at 69.3%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

OO 5886 quarter by quarter

OO 5886 did not run the same all year. Its best quarter was Oct–Dec 2025 at 80.0% on time and its weakest Jul–Sep 2025 at 56.5%, a swing of 24 points on roughly 82 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.

Oct–Dec 202590 flights80.0%
Jan–Mar 202653 flights76.5%

Scale runs 50% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5886 did best on Sunday at 76.6% on time and worst on Monday at 61.7%. Each day rests on about 47 flights, so a gap of 15 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5886 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 6,677 reported delay minutes.

Late-arriving aircraft
34%
National Airspace System
27%
Carrier
24%
Extreme weather
15%

Extreme weather accounts for 15% 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 2.4 times the usual weather exposure. The split is drawn from 6,677 delay minutes reported on OO 5886.

Cancellations sit at 0.92% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

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. 13.0% 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 637 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.

Every one of the 326 flights under OO 5886 in the data flew DEN to SGF. 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. 326 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 5886

For a booking, OO 5886 is a flight to put a long connection behind. 13.0% 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.
