These figures cover 342 flights between September 2025 and August 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.

- 44%Carrier
- 38%National Airspace System
- 16%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,792 of the 4,038 delay minutes reported here. The split is drawn from 4,038 delay minutes reported on YX 5761.
Cancellations run at 3.80%, against 1.89% nationally. That is about one flight in 25 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
7.9% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.
Every one of the 342 flights under YX 5761 in the data flew LGA to BOS. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 342 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 5761
For a booking, the cancellation rate is the figure to plan around on YX 5761: 3.80% of its 342 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
