Delay causes
Why AS 706 runs late
Late-arriving aircraft accounts for 54% of the 4,030 delay minutes carriers reported here, and the remaining four split what is left.
- 54%Late-arriving aircraft
- 36%Carrier
- 6%National Airspace System
- 4%Extreme weather
54% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,030 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 4,030 delay minutes reported on AS 706.
Cancellations sit at 2.06% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
8.1% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
The 672 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 PDX to SAN (1), but none flew often enough under AS 706 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to SEA to OAK only.
One caution: this is a thin sample. 291 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 706
For a booking, read AS 706 as 75.1% on time with 2.06% cancelled over 291 flights. Those are rates from the past twelve months, not a forecast for any particular day.
