These figures cover 294 flights between September 2025 and August 2026. The median arrival is 9 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 3669 runs late
Late-arriving aircraft accounts for 62% of the 2,726 delay minutes carriers reported here, and the remaining four split what is left.
- 62%Late-arriving aircraft
- 27%National Airspace System
- 11%Carrier
62% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 2,726 reported delay minutes here, that single category outweighs weather by 62 to one. The split is drawn from 2,726 delay minutes reported on YX 3669.
Cancellations run at 3.06%, against 1.89% nationally. That is roughly one flight in 30 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 4.9% 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 645 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 seven other city pairs in the data, including PWM to EWR (26), IAD to SYR (10) and IAD to BTV (10), but none flew often enough under YX 3669 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to IND only.
One caution: this is a thin sample. 294 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 3669
For a booking, the cancellation rate is the figure to plan around on YX 3669: 3.06% of its 294 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
