DCA in June carries a cancellation problem, not just a delay problem: 4.9% of scheduled flights never operate, against 1.6% 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 11,953 flights, of which Republic Airways flew 2,116 at 77.7% on time.

Republic Airways is the most reliable of the eight carriers covered here at 77.7% on time across 2,116 flights.

These figures cover 11,953 departures from Ronald Reagan Washington National in June 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.

Departure window

The best time of day to leave DCA in June

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 32 points, against 15 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

5am–8am1,547 flights90.3%
8am–11am2,475 flights81.8%
11am–2pm1,939 flights74.5%
2pm–5pm2,179 flights64.0%
5pm–8pm2,211 flights58.1%
8pm–5am1,602 flights61.4%

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

The 5pm–8pm window is where this operation falls apart: 58.1% on time, against 90.3% 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 2,475 flights scheduled in it.

Across the week, Tuesday is the strongest day at 80.1% on time and Sunday the weakest at 60.4%. 20 points is a smaller lever than departure hour, but it is free.

Carrier by carrier

Which airlines ran best at DCA in June

The choice of carrier is not cosmetic here. Republic Airways arrives on time 77.7% of the time; Southwest Airlines manages 62.9%. Sample sizes sit next to every figure, because a two-point gap across 1,344 flights means less than a ten-point one.

Delay causes

What held DCA up in June

One category carries most of the weight here. Late-arriving aircraft accounts for 45% of the 282,000 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
21%
Extreme weather
8%
Security
0%

45% 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 282,000 reported delay minutes here, that single category outweighs weather by 6 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 282,424 reported delay minutes.

Cancellations run at 4.94%, against 1.65% 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. 12.6% of arrivals land a full hour or more behind schedule, against 9.7% 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.
