Why OO 6275 runs late

Carrier accounts for 87% of the 8,997 delay minutes carriers reported here, and the remaining four split what is left.

The largest share of delay minutes, 87%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 7,782 of the 8,997 delay minutes reported here. The split is drawn from 8,997 delay minutes reported on OO 6275.

Cancellations are rare at 0.27%, 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

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 365 flights under OO 6275 in the data flew FAT 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. 365 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 6275

For a booking, OO 6275 has one of the better records a US domestic flight can show: 86.5% on time and 0.27% cancelled. That is a base rate, not a promise about any single day.
