Historical statistics for July 2025 to June 2026, not live status. For today’s YX 5732, 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 5732 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 267 flights, with a median arrival 11 minutes early.

Set against the rest of the country, YX 5732's record is 10 points better than the US average of 77.6%. That gap is worth roughly 98 fewer late arrivals for every thousand flights.

These figures cover 267 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 5732 flies

YX 5732 is scheduled to leave Boston (BOS) at 09:00 local time and reach New York (LGA) at 10:20. That slot held for 263 of the 267 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 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 5732 runs 3 points better at 87.4%. 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 5732 quarter by quarter

YX 5732 did not run the same all year. Its best quarter was Apr–Jun 2026 at 97.5% on time and its weakest Jan–Mar 2026 at 77.6%, a swing of 20 points on roughly 67 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 5732 ranged from 81.6% on Tuesday to 93.3% on Monday. With about 38 flights behind each day, a spread of 12 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 5732 runs late

One category carries most of the weight here. Carrier accounts for 50% of the 2,011 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.

National Airspace System
33%
Late-arriving aircraft
16%
Extreme weather
1%

The largest share of delay minutes, 50%, 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 1,010 of the 2,011 delay minutes reported here. The split is drawn from 2,011 delay minutes reported on YX 5732.

Cancellations run at 4.87%, against 1.81% 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.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.9% 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 AVL to BOS (12), BOS to AVL (12) and BOS to DCA (1), but none flew often enough under YX 5732 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BOS to LGA only.

One caution: this is a thin sample. 267 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 5732

For a booking, the cancellation rate is the figure to plan around on YX 5732: 4.87% of its 267 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
