These figures cover 350 flights between September 2025 and August 2026. The median arrival is 4 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 3530 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 3,396 reported delay minutes.
- 42%Late-arriving aircraft
- 30%National Airspace System
- 25%Carrier
- 4%Extreme weather
42% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,396 reported delay minutes here, that single category outweighs weather by 11 to one. The split is drawn from 3,396 delay minutes reported on YX 3530.
Cancellations sit at 1.71% against a national 1.89%, which is ordinary. Diversions add another 0.29%.
Connections and routes
What a delay on this flight costs
5.2% 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 55 minutes, which a normal layover absorbs.
The same number turns up on two other city pairs in the data, including JAX to EWR (7) and EWR to JAX (5), but none flew often enough under YX 3530 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IND to IAD only.
One caution: this is a thin sample. 350 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 3530
For a booking, read YX 3530 as 81.9% on time with 1.71% cancelled over 350 flights. Those are rates from the past twelve months, not a forecast for any particular day.
