Historical statistics for March 2026, not live status or a forecast for this year’s March. For today’s conditions at DCA, see live FAA status.

DCA in March carries a cancellation problem, not just a delay problem: 5.0% of scheduled flights never operate, against 2.9% nationally. Of the ones that do fly, about seven flights in ten arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 12,204 flights, of which United Airlines flew 538 at 80.4% on time.

United Airlines is the most reliable of the eight carriers covered here at 80.4% on time across 538 flights.

DCA across all twelve months

These figures cover 12,204 departures from Ronald Reagan Washington National in March 2026. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.

Against the year

March next to DCA's other months

Against DCA's own year, March ran 3 points worse than the twelve-month rate of 73.3%, which makes it number ten of twelve months, best first. Either side of it, February ran 71.1% on time and April 77.0%, so a trip moved by a few weeks would have landed in a better stretch.

Departure window

The best time of day to leave DCA in March

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 31 points, against 18 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am1,622 flights88.4%
  • 8am–11am2,508 flights79.7%
  • 11am–2pm1,889 flights75.9%
  • 2pm–5pm2,304 flights62.8%
  • 5pm–8pm2,173 flights57.3%
  • 8pm–5am1,708 flights57.7%

Scale runs 50% to 95%. Rows with fewer than 30 flights show a dash.

The 5pm–8pm window is where this operation falls apart: 57.3% on time, against 88.4% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 8am–11am window is the busiest, with 2,508 flights scheduled in it.

Across the week, Sunday is the strongest day at 76.0% on time and Friday the weakest at 62.0%. 14 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at DCA in March

The choice of carrier is not cosmetic here. United Airlines arrives on time 80.4% of the time; PSA Airlines manages 62.8%. Sample sizes sit next to every figure, because a two-point gap across 3,509 flights means less than a ten-point one.

Delay causes

What held DCA up in March

One category carries most of the weight here. Late-arriving aircraft accounts for 49% of the 292,000 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.

  • Late-arriving aircraft

  • Carrier
    25%
  • National Airspace System

  • Extreme weather
    5%
  • Security
    0%

49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 292,000 reported delay minutes here, that single category outweighs weather by 9 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 291,998 reported delay minutes.

Cancellations run at 4.98%, against 2.90% nationally. That is about one flight in twenty cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 13.1% of arrivals land a full hour or more behind schedule, against 9.5% 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.

What to do with this

Flying from DCA in March

For a March trip through DCA: plan on this being one of the airport's harder months. The 5am–8am departures held up best at 88.4% on time, and with 13.1% of arrivals an hour or more late, a connection here deserves more slack than the same trip in September would.
