These figures cover 335 flights between September 2025 and August 2026. The median arrival is 10 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.

Delay causes

Why YX 4716 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,864 reported delay minutes.

National Airspace System

Carrier
31%
Late-arriving aircraft

Extreme weather

Security

42% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,201 minutes out of 2,864, against a national NAS share of 21%. The split is drawn from 2,864 delay minutes reported on YX 4716.

Cancellations sit at 1.49% against a national 1.89%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

6.1% 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 a little over an hour, which a normal layover absorbs.

The 818 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 two other city pairs in the data, including BOS to ILM (27) and ILM to BOS (27), but none flew often enough under YX 4716 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IND to BOS only.

One caution: this is a thin sample. 335 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 4716

For a booking, YX 4716 has one of the better records a US domestic flight can show: 88.2% on time and 1.49% cancelled. That is a base rate, not a promise about any single day.
