Historical statistics for July 2025 to June 2026, not live status. For today’s AS 2, check with Alaska Airlines.

AS 2 draws a C. About one flight in three arrives at least 15 minutes late, and the typical late arrival is about an hour behind schedule. Build slack into anything you connect to. That rests on 364 flights, with a median arrival 9 minutes early.

The national on-time rate over the same period is 77.6%, so AS 2 runs 11 points behind the country as a whole. Across a thousand flights that is about 106 extra late arrivals.

These figures cover 364 flights between July 2025 and June 2026. Beyond the headline rate, 11.0% 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 2 flies

AS 2 flies SEA to DCA without a single fixed slot. Its most common scheduled departure was 13:55, used on 56 of 364 flights, with 13:58 (50 flights) and 13:56 (50 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 13:55 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AS 2 runs 12 points worse at 67.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

AS 2 quarter by quarter

AS 2 did not run the same all year. Its best quarter was Apr–Jun 2026 at 78.0% on time and its weakest Jul–Sep 2025 at 44.6%, a swing of 33 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 2 did best on Saturday at 80.0% on time and worst on Friday at 58.0%. Each day rests on about 52 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why AS 2 runs late

One category carries most of the weight here. National Airspace System accounts for 62% of the 7,048 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.

62% 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 4,381 minutes out of 7,048, against a national NAS share of 21%. The split is drawn from 7,048 delay minutes reported on AS 2.

Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 1.37%.

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. 11.0% 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 2,329 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 364 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. 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.

What to do with this

Booking AS 2

For a booking, AS 2 is one of the weaker ways to fly SEA to DCA: 15 points below the route as a whole. If the schedule allows, compare it with the other departures listed on the route page before settling on this one.
