In the other direction, 44 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 PHX.

- 90%Carrier
- 7%National Airspace System
- 3%Late-arriving aircraft
- 0%Extreme weather
The largest share of delay minutes, 90%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 7,063 of the 7,842 delay minutes reported here. The split is drawn from 7,842 delay minutes reported on OO 6328.
Cancellations are rare at 0.00%, below the national 1.89% 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
9.1% 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.
Every one of the 364 flights under OO 6328 in the data flew DRO to PHX. 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. 364 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.
