Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5693, 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 5693 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 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs about an hour. That rests on 327 flights, with a median arrival 11 minutes early.

Set against the rest of the country, YX 5693's record is 10 points better than the US average of 77.6%. That gap is worth roughly 95 fewer late arrivals for every thousand flights.

These figures cover 327 flights between July 2025 and June 2026. The median arrival is 11 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 5693 flies

YX 5693 flies BOS to DCA without a single fixed slot. Its most common scheduled departure was 09:35, used on 102 of 327 flights, with 09:30 (69 flights) and 09:15 (45 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 09:35 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 5693 runs 3 points better at 87.1%. 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 5693 quarter by quarter

YX 5693 did not run the same all year. Its best quarter was Jul–Sep 2025 at 92.5% on time and its weakest Jan–Mar 2026 at 78.8%, a swing of 14 points on roughly 82 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 5693 did best on Tuesday at 95.7% on time and worst on Friday at 80.0%. Each day rests on about 47 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 5693 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,274 reported delay minutes.

Carrier
40%
National Airspace System
37%
Extreme weather
14%
Late-arriving aircraft
9%

Extreme weather accounts for 14% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.2 times the usual weather exposure. The split is drawn from 2,274 delay minutes reported on YX 5693.

Cancellations run at 2.75%, against 1.81% nationally. That is roughly 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 3.5% 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.

YX 5693 is not only a BOS to DCA flight. It also flew DCA to BOS (286 flights, 85.0% on time) often enough to be scored on its own. Airlines attach one number to several legs of an aircraft's day, and each leg keeps its own record here, so check which city pair is on your booking before reading a rate.

One caution: this is a thin sample. 327 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.
