YX 5732 earns an A−. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 9 points better than the national rate of 77.3%. When something does go wrong the average delay runs about an hour. That rests on 276 flights, with a median arrival 11 minutes early.

These figures cover 276 flights between September 2025 and August 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.

When YX 5732 flies

YX 5732 is scheduled to leave Boston (BOS) at 09:00 local time and reach New York (LGA) at 10:30. That slot held for 272 of the 276 scheduled departures in the data, so the figures below describe one steady operation rather than a number that moved around the clock.

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 69 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.

The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,051 of the 2,416 delay minutes reported here. The split is drawn from 2,416 delay minutes reported on YX 5732.

Cancellations run at 6.16%, against 1.89% 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

Badly late arrivals are rare here: only 4.6% land an hour or more behind schedule, against 8.3% 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 one other city pair in the data, including 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. 276 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: 6.16% of its 276 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
