Historical statistics for July 2025 to June 2026, not live status. For today’s OO 5678, 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.

These figures cover 358 flights between July 2025 and June 2026. Beyond the headline rate, 8.8% 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 5678 flies

OO 5678 flies MOT to DEN without a single fixed slot. Its most common scheduled departure was 07:00, used on 141 of 358 flights, with 07:20 (110 flights) and 07:15 (53 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and OO 5678 runs 8 points worse at 81.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

OO 5678 quarter by quarter

OO 5678 did not run the same all year. Its best quarter was Oct–Dec 2025 at 87.6% on time and its weakest Jul–Sep 2025 at 76.1%, a swing of 12 points on roughly 90 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 5678 did best on Wednesday at 88.2% on time and worst on Saturday at 75.0%. Each day rests on about 51 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5678 runs late

One category carries most of the weight here. Carrier accounts for 57% of the 10,000 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.

Carrier
57%
Late-arriving aircraft
24%
Extreme weather
15%
National Airspace System
4%

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 10,448 delay minutes reported on OO 5678.

Cancellations sit at 1.40% against a national 1.81%, which is ordinary. Diversions add another 0.28%.

Connections and routes

What a delay on this flight costs

8.8% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 2.7 hours, which a normal layover absorbs.

The 604 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.

The same number turns up on one other city pair in the data, including ORD to CVG (2), but none flew often enough under OO 5678 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MOT to DEN only.

One caution: this is a thin sample. 358 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.
