Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5682, check with Republic Airways. Republic Airways flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

YX 5682 earns a D−, which is as low as this site's scale goes for a reason. Only 56.3% of flights arrive inside the 15-minute window, 21 points worse than the national rate of 77.6%. Late arrivals average a little over an hour. Treat any tight connection here as a coin flip. That rests on 268 flights, with a median arrival 4 minutes late.

The national on-time rate over the same period is 77.6%, so YX 5682 runs 21 points behind the country as a whole. Across a thousand flights that is about 213 extra late arrivals.

These figures cover 268 flights between July 2025 and June 2026. Beyond the headline rate, 22.6% 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 YX 5682 flies

YX 5682 flies DCA to BOS without a single fixed slot. Its most common scheduled departure was 16:45, used on 94 of 268 flights, with 17:00 (84 flights) and 16:50 (34 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 16:45 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and YX 5682 runs 16 points worse at 56.3%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

YX 5682 quarter by quarter

YX 5682 did not run the same all year. Its best quarter was Oct–Dec 2025 at 60.3% on time and its weakest Jul–Sep 2025 at 48.1%, a swing of 12 points on roughly 89 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, YX 5682 did best on Tuesday at 63.4% on time and worst on Friday at 39.0%. Each day rests on about 38 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 5682 runs late

One category carries most of the weight here. National Airspace System accounts for 50% of the 8,495 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
34%
Carrier
13%
Extreme weather
2%

34% 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 8,495 reported delay minutes here, that single category outweighs weather by 16 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 8,495 delay minutes reported on YX 5682.

Cancellations run at 5.97%, against 1.81% nationally. That is roughly 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 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. 22.6% 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 same number turns up on five other city pairs in the data, including BOS to DCA (247), CMH to BOS (25) and DCA to JFK (15), but none flew often enough under YX 5682 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to BOS only.

One caution: this is a thin sample. 268 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 YX 5682

For a booking, the cancellation rate is the figure to plan around on YX 5682: 5.97% of its 268 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
