These figures cover 325 flights between July 2025 and June 2026. Beyond the headline rate, 8.4% 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 5113 flies

OO 5113 flies DEN to SGU without a single fixed slot. Its most common scheduled departure was 11:15, used on 172 of 325 flights, with 11:20 (129 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 11:15 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and OO 5113 runs 5 points worse at 74.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

OO 5113 quarter by quarter

OO 5113 did not run the same all year. Its best quarter was Jul–Sep 2025 at 81.1% on time and its weakest Apr–Jun 2026 at 63.3%, a swing of 18 points on roughly 81 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 5113 did best on Friday at 85.1% on time and worst on Monday at 63.0%. Each day rests on about 46 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why OO 5113 runs late

One category carries most of the weight here. Carrier accounts for 51% of the 4,918 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.

Late-arriving aircraft
30%
National Airspace System
18%
Extreme weather
2%

The largest share of delay minutes, 51%, 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 2,491 of the 4,918 delay minutes reported here. The split is drawn from 4,918 delay minutes reported on OO 5113.

Cancellations are rare at 0.00%, below the national 1.81% and low enough to earn the plus on the grade. Almost no flights are called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

8.4% 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 an hour, which a normal layover absorbs.

The 517 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 three other city pairs in the data, including RKS to DEN (37), SGU to DEN (24) and MGW to ORD (1), but none flew often enough under OO 5113 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DEN to SGU only.

One caution: this is a thin sample. 325 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
