Historical statistics for July 2025 to June 2026, not live status. For today’s OO 4676, 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.
OO 4676 sits in the middle of the pack with a C. About seven flights in ten arrive on time by the DOT's definition, 8 points worse than the national rate of 77.6%. The late ones land close to two hours behind schedule. That rests on 321 flights, with a median arrival 5 minutes early.
The national on-time rate over the same period is 77.6%, so OO 4676 runs 8 points behind the country as a whole. Across a thousand flights that is about 76 extra late arrivals.

These figures cover 321 flights between July 2025 and June 2026. Beyond the headline rate, 17.9% 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

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 4676 runs level with that at 70.0%. 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 4676 quarter by quarter
OO 4676 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.5% on time and its weakest Jul–Sep 2025 at 49.4%, a swing of 38 points on roughly 80 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 4676 did best on Wednesday at 80.0% on time and worst on Saturday at 59.1%. Each day rests on about 46 flights, so a gap of 21 points is worth noticing but could still narrow in another year.
Delay causes
Why OO 4676 runs late
One category carries most of the weight here. Carrier accounts for 45% of the 12,000 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.
- 45%Carrier
- 32%Late-arriving aircraft
- 19%National Airspace System
- 4%Extreme weather
The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 5,196 of the 12,000 delay minutes reported here. The split is drawn from 11,624 delay minutes reported on OO 4676.
Cancellations sit at 1.56% against a national 1.81%, which is ordinary. Diversions add another 0.93%.
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. 17.9% 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 771 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 six other city pairs in the data, including BNA to ORD (31), DFW to ORD (6) and CHA to DEN (3), but none flew often enough under OO 4676 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to LIT only.
One caution: this is a thin sample. 321 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 4676
For a booking, OO 4676 is a flight to put a long connection behind. 17.9% 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.
