Share of 319 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 70 departures that left 15 minutes late or more, only 7 made it up before arrival. In the other direction, 19 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SGU.

Delay causes
Why OO 5113 runs late
Carrier accounts for 50% of the 4,462 delay minutes carriers reported here, and the remaining four split what is left.
- 50%Carrier
- 30%Late-arriving aircraft
- 19%National Airspace System
- 2%Extreme weather
The largest share of delay minutes, 50%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,213 of the 4,462 delay minutes reported here. The split is drawn from 4,462 delay minutes reported on OO 5113.
Cancellations are rare at 0.31%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
7.2% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about 55 minutes, 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.
The same number turns up on three other city pairs in the data, including SGU to DEN (81), RKS to DEN (37) 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. 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.
