These figures cover 339 flights between July 2025 and June 2026. Beyond the headline rate, 13.4% 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 5097 flies

OO 5097 flies DEN to DIK without a single fixed slot. Its most common scheduled departure was 20:30, used on 72 of 339 flights, with 20:40 (70 flights) and 20:20 (61 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 20:30 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and OO 5097 runs 3 points better at 73.9%. 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 5097 quarter by quarter

OO 5097 did not run the same all year. Its best quarter was Oct–Dec 2025 at 86.4% on time and its weakest Jul–Sep 2025 at 56.5%, a swing of 30 points on roughly 85 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.

Jul–Sep 202591 flights56.5%
Oct–Dec 202590 flights86.4%
Jan–Mar 202690 flights78.6%

Scale runs 50% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, OO 5097 did best on Tuesday at 81.6% on time and worst on Friday at 62.5%. Each day rests on about 48 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5097 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 11,000 reported delay minutes.

Late-arriving aircraft
31%
Carrier
29%
Extreme weather
21%
National Airspace System

Security
0%

Extreme weather accounts for 21% 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 11,474 delay minutes reported on OO 5097.

Cancellations run at 3.24%, against 1.81% nationally. That is about 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. 13.4% 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 four other city pairs in the data, including HYS to DEN (26), LBF to DEN (14) and SGU to DEN (4), but none flew often enough under OO 5097 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to DIK only.

One caution: this is a thin sample. 339 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 5097

For a booking, the cancellation rate is the figure to plan around on OO 5097: 3.24% of its 339 scheduled flights did not operate. A late arrival costs about 2.3 hours, but a cancellation costs the day, so leave a later option open.
