Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5710, 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 5710 earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 14 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 258 flights, with a median arrival 12 minutes early.

Set against the rest of the country, YX 5710's record is 14 points better than the US average of 77.6%. That gap is worth roughly 144 fewer late arrivals for every thousand flights.

These figures cover 258 flights between July 2025 and June 2026. The median arrival is 12 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When YX 5710 flies

YX 5710 is scheduled to leave Washington (DCA) at 06:00 local time and reach Boston (BOS) at 07:41. That slot held for 258 of the 258 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 5710 runs 3 points better at 92.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

YX 5710 quarter by quarter

YX 5710 did not run the same all year. Its best quarter was Jul–Sep 2025 at 95.6% on time and its weakest Jan–Mar 2026 at 83.9%, a swing of 12 points on roughly 65 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.

Jul–Sep 202568 flights95.6%
Oct–Dec 202557 flights94.6%
Jan–Mar 202662 flights83.9%
Apr–Jun 202671 flights93.0%

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, YX 5710 ranged from 85.4% on Monday to 95.9% on Wednesday. With about 37 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 5710 runs late

One category carries most of the weight here. Carrier accounts for 76% of the 1,258 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.

Carrier
76%
National Airspace System
19%
Late-arriving aircraft
4%

The largest share of delay minutes, 76%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 957 of the 1,258 delay minutes reported here. The split is drawn from 1,258 delay minutes reported on YX 5710.

Cancellations run at 2.71%, against 1.81% nationally. That is about one flight in 40 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

Badly late arrivals are rare here: only 3.6% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The same number turns up on three other city pairs in the data, including SAV to BOS (7), BOS to SAV (7) and DTW to GRR (2), but none flew often enough under YX 5710 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. 258 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 5710

For a booking, the cancellation rate is the figure to plan around on YX 5710: 2.71% of its 258 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
