Across the year
AS 2 quarter by quarter

Delay causes
Why AS 2 runs late
National Airspace System accounts for 59% of the 5,976 delay minutes carriers reported here, and the remaining four split what is left.
- 59%National Airspace System
- 20%Late-arriving aircraft
- 13%Carrier
- 8%Extreme weather
59% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 3,541 minutes out of 5,976, against a national NAS share of 21%. The split is drawn from 5,976 delay minutes reported on AS 2.
Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 1.38%.
Connections and routes
What a delay on this flight costs
9.6% 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 2,329 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 363 flights under AS 2 in the data flew SEA to DCA. 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. 363 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.
