Delay causes
Why AS 1447 runs late
Late-arriving aircraft accounts for 60% of the 7,803 delay minutes carriers reported here, and the remaining four split what is left.
- 60%Late-arriving aircraft
- 18%National Airspace System
- 11%Carrier
- 10%Extreme weather
60% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,803 reported delay minutes here, that single category outweighs weather by 6 to one. The split is drawn from 7,803 delay minutes reported on AS 1447.
Cancellations sit at 1.71% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
11.8% 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.
At 1,723 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 293 flights under AS 1447 in the data flew ORD to SAN. 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. 293 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 AS 1447
