These figures cover 334 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.

Across the year

YX 4797 quarter by quarter

Delay causes

Why YX 4797 runs late

Carrier accounts for 44% of the 1,968 delay minutes carriers reported here, and the remaining four split what is left.

44%
National Airspace System
25%
Extreme weather
16%
Late-arriving aircraft
15%

Extreme weather accounts for 16% 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 2.6 times the usual weather exposure. The split is drawn from 1,968 delay minutes reported on YX 4797.

Cancellations run at 2.69%, against 1.89% nationally. That is about 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 2.5% 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 660 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.

Every one of the 334 flights under YX 4797 in the data flew IND to LGA. 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. 334 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 4797

For a booking, the cancellation rate is the figure to plan around on YX 4797: 2.69% of its 334 scheduled flights did not operate. A late arrival costs roughly 55 minutes, but a cancellation costs the day, so leave a later option open.
