Across the year
AS 14 quarter by quarter
AS 14 did not run the same all year. Its best quarter was Apr–Jun 2026 at 81.1% on time and its weakest Jan–Mar 2026 at 63.2%, a swing of 18 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

By weekday, AS 14 did best on Tuesday at 78.8% on time and worst on Thursday at 56.0%. Each day rests on about 52 flights, so a gap of 23 points is worth noticing but could still narrow in another year.

| 7 September 2025 | 4 hours 11 minutes | Late-arriving aircraft |

Delay causes
Why AS 14 runs late
National Airspace System accounts for 53% of the 6,596 delay minutes carriers reported here, and the remaining four split what is left.

- 29%Late-arriving aircraft
- 10%Carrier
- 7%Extreme weather
- 0%Security
53% 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 3,476 minutes out of 6,596, against a national NAS share of 21%. The split is drawn from 6,596 delay minutes reported on AS 14.
Cancellations sit at 1.10% against a national 1.89%, which is ordinary. Diversions add another 0.55%.
Connections and routes
What a delay on this flight costs
11.5% 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 2,276 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 14 in the data flew SAN 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.
What to do with this
Booking AS 14
For a booking, read AS 14 as 70.0% on time with 1.10% cancelled over 363 flights. Those are rates from the past twelve months, not a forecast for any particular day.
