Delay causes
Why YX 3403 runs late
Late-arriving aircraft accounts for 43% of the 8,191 delay minutes carriers reported here, and the remaining four split what is left.
- 43%Late-arriving aircraft
- 39%Carrier
- 14%National Airspace System
- 3%Extreme weather
43% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 8,191 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 8,191 delay minutes reported on YX 3403.
Cancellations run at 6.73%, against 1.89% nationally. That is about one flight in fifteen 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
9.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
The same number turns up on five other city pairs in the data, including PWM to EWR (20), ATL to EWR (19) and EWR to SAV (2), but none flew often enough under YX 3403 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. 342 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 3403
For a booking, the cancellation rate is the figure to plan around on YX 3403: 6.73% of its 342 scheduled flights did not operate. A late arrival costs about 2.4 hours, but a cancellation costs the day, so leave a later option open.
