Delay causes
Why OO 5812 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 1,387 reported delay minutes.
- 40%National Airspace System
- 36%Carrier
- 19%Late-arriving aircraft
- 5%Extreme weather
The largest share of delay minutes, 36%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 506 of the 1,387 delay minutes reported here. The split is drawn from 1,387 delay minutes reported on OO 5812.
Cancellations sit at 1.31% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 2.3% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 616 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 one other city pair in the data, including COS to DEN (50), but none flew often enough under OO 5812 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to XNA to DEN only.
One caution: this is a thin sample. 305 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 5812
For a booking, OO 5812 has one of the better records a US domestic flight can show: 92.0% on time and 1.31% cancelled. That is a base rate, not a promise about any single day.
