These figures cover 363 flights between July 2025 and June 2026. Beyond the headline rate, 10.9% 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 6 flies
AS 6 flies LAX to DCA without a single fixed slot. Its most common scheduled departure was 13:31, used on 50 of 363 flights, with 12:47 (45 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 13:31 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and AS 6 runs 3 points worse at 75.7%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year
AS 6 quarter by quarter
AS 6 did not run the same all year. Its best quarter was Apr–Jun 2026 at 83.1% on time and its weakest Jul–Sep 2025 at 69.2%, a swing of 14 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.

- Oct–Dec 202591 flights79.1%
- Jan–Mar 202690 flights71.3%
- Apr–Jun 202690 flights83.1%
Scale runs 60% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, AS 6 did best on Saturday at 88.2% on time and worst on Wednesday at 62.7%. Each day rests on about 52 flights, so a gap of 26 points is worth noticing but could still narrow in another year.
Delay causes
Why AS 6 runs late
One category carries most of the weight here. National Airspace System accounts for 56% of the 6,504 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.
- 56%National Airspace System
- 25%Late-arriving aircraft
- 19%Carrier
- 0%Extreme weather
56% 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 3,659 minutes out of 6,504, against a national NAS share of 21%. The split is drawn from 6,504 delay minutes reported on AS 6.
Cancellations are rare at 0.83%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
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. 10.9% 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 2,311 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 6 in the data flew LAX 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 6
