C−GRADE

This route carries a cancellation problem, not just a delay problem: 6.5% of scheduled flights never operate, against 1.8% 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 1,110 DCA to BGR flights, with a median arrival 2 minutes early.

Best time to fly DCA to BGR: a 8am–11am departure, ideally on a Saturday. Flights in that window arrived on time 77.1% of the time and Saturday flights 75.7%, against 69.2% for the route overall.

The national on-time rate over the same period is 77.6%, so this route runs 8 points behind the country as a whole. Across a thousand flights that is about 84 extra late arrivals.

These figures cover 1,110 flights between July 2025 and June 2026. Beyond the headline rate, 11.8% 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.

Carrier by carrier

Which airline is most reliable on DCA to BGR

Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window

The best time of day to leave

Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

  • 5am–8am
  • 8am–11am367 flights77.1%
  • 11am–2pm32 flights61.3%
  • 2pm–5pm353 flights63.5%
  • 5pm–8pm8 flights
  • 8pm–5am350 flights67.3%

Scale runs 55% to 85%. Rows with fewer than 30 flights show a dash.

The weak window here is the middle of the day, not the evening: 11am–2pm runs 61.3% on time against 77.1% for 8am–11am. That shape usually means a departure bank rather than an accumulating delay, so the recovery later in the afternoon is real rather than noise. The 8am–11am window is the busiest, with 367 flights scheduled in it.

Across the year

When delays peak on this route

This route's year swings by 34 points from best month to worst, which is wide. An annual average tells you very little about the week you are actually flying, so read the strip rather than the headline if your dates are fixed.

Darker means more delays. Figures are on-time percentages.October best, February worst

February is the weak month at 55.3% on time, against 89.0% in October. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. June was the busiest month here, with 115 flights.

Across the week, Saturday is the strongest day at 75.7% on time and Monday the weakest at 66.0%. 10 points is a smaller lever than departure hour, but it is free.

Delay causes

Why this route gets delayed

One category carries most of the weight here. Late-arriving aircraft accounts for 52% of the 23,000 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
    52%
  • Carrier
    33%
  • National Airspace System
    10%
  • Extreme weather
    5%
  • Security
    1%

52% 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 23,000 reported delay minutes here, that single category outweighs weather by 10 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 23,185 reported delay minutes.

The practical consequence: the 8am–11am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 77.1% on time here.

Cancellations run at 6.49%, against 1.81% nationally. That is about one flight in fifteen 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.

Connections and stage length

What a delay here actually costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 11.8% 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.

The 590 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The return leg runs 69.5% on time across 1,111 flights, within half a point of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

The sample behind these figures is 1,110 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this

Booking this route

Put together: the delay figures matter less here than the 6.49% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 8am–11am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 1,034 completed flights over 12 months sit behind that.

Common questions

DCA to BGR questions

How often is DCA to BGR delayed?

Roughly one flight in three arrives at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 30.8% of the 1,110 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.

How reliable is DCA to BGR compared with the rest of the country?

69.2% of flights arrive on time here against a national 77.6%, a difference of 8 points against it. That is worth a C− on this site's grading scale.

What time of day has the fewest delays on DCA to BGR?

The 8am–11am departure window is the strongest at 77.1% on time. The 11am–2pm window is the weakest at 61.3%, 16 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.

How bad are February delays on DCA to BGR?

February is the weakest month at 55.3% on time, compared with 89.0% in October. Across the year that is 34 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.

Direction matters. DCA to BGR and BGR to DCA are scored separately because they are separate operations, with different departure banks and different aircraft. Compare the return leg.
