These figures cover 303 flights between September 2025 and August 2026. The median arrival is 15 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 3477 quarter by quarter
YX 3477 did not run the same all year. Its best quarter was Jan–Mar 2026 at 85.7% on time and its weakest Jul–Sep 2026 at 60.0%, a swing of 26 points on roughly 76 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Delay causes
Why YX 3477 runs late
Late-arriving aircraft accounts for 67% of the 3,302 delay minutes carriers reported here, and the remaining four split what is left.
- 67%Late-arriving aircraft
- 15%National Airspace System
- 13%Carrier
- 6%Extreme weather
67% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 3,302 reported delay minutes here, that single category outweighs weather by 12 to one. The split is drawn from 3,302 delay minutes reported on YX 3477.
Cancellations run at 8.25%, against 1.89% nationally. That is about one flight in twelve 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
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 about an hour, which a normal layover absorbs.
The same number turns up on nine other city pairs in the data, including RDU to EWR (53), STL to EWR (35) and ORD to ROC (31), but none flew often enough under YX 3477 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to PIT only.
One caution: this is a thin sample. 303 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 3477
For a booking, the cancellation rate is the figure to plan around on YX 3477: 8.25% of its 303 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
