Time lost at the gate mostly stays lost. Of 73 departures that left 15 minutes late or more, only 5 made it up before arrival. In the other direction, 22 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 SGF.

Delay causes
Why OO 5886 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 6,086 reported delay minutes.
- 36%Late-arriving aircraft
- 35%Carrier
- 24%National Airspace System
- 6%Extreme weather
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 6,086 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 6,086 delay minutes reported on OO 5886.
Cancellations sit at 1.23% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
10.3% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The 637 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.
Every one of the 325 flights under OO 5886 in the data flew DEN to SGF. The number was not reused on any other city pair, which makes this a clean record of one route.
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.
