These figures cover 364 flights between July 2025 and June 2026. Beyond the headline rate, 10.6% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When AS 14 flies

AS 14 flies SAN to DCA without a single fixed slot. Its most common scheduled departure was 12:42, used on 106 of 364 flights, with 13:41 (45 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

A 12:42 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AS 14 runs 11 points worse at 68.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

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 Jul–Sep 2025 at 55.6%, a swing of 25 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 Monday at 78.4% on time and worst on Thursday at 57.1%. Each day rests on about 52 flights, so a gap of 21 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 14 runs late

One category carries most of the weight here. National Airspace System accounts for 57% of the 6,658 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

57% 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 3,779 minutes out of 6,658, against a national NAS share of 21%. The split is drawn from 6,658 delay minutes reported on AS 14.

Cancellations sit at 1.37% against a national 1.81%, which is ordinary. Diversions add another 0.55%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.6% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum 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 364 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. 364 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.
