These figures cover 284 flights between September 2025 and August 2026. The median arrival is 6 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.

39% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,516 reported delay minutes here, that single category outweighs weather by 8 to one. The split is drawn from 3,516 delay minutes reported on YX 4592.
Cancellations run at 4.93%, against 1.89% 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
7.4% 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.
The 665 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The same number turns up on four other city pairs in the data, including LGA to ATL (38), JFK to IND (37) and LGA to PIT (25), but none flew often enough under YX 4592 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IND to JFK only.
One caution: this is a thin sample. 284 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 4592
For a booking, the cancellation rate is the figure to plan around on YX 4592: 4.93% of its 284 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
