These figures cover 283 flights between September 2025 and August 2026. The median arrival is 7 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 3523 quarter by quarter

Delay causes
Why YX 3523 runs late
Late-arriving aircraft accounts for 56% of the 4,283 delay minutes carriers reported here, and the remaining four split what is left.
- 56%Late-arriving aircraft
- 23%Carrier
- 19%National Airspace System
- 2%Extreme weather
56% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,283 reported delay minutes here, that single category outweighs weather by 30 to one. The split is drawn from 4,283 delay minutes reported on YX 3523.
Cancellations sit at 1.06% against a national 1.89%, which is ordinary. Diversions add another 0.00%.
Connections and routes
What a delay on this flight costs
6.8% 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 642 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 IND to ORD (24), IAD to CVG (21) and IND to EWR (21), but none flew often enough under YX 3523 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to RIC only.
One caution: this is a thin sample. 283 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 3523
