Delay causes
Why YX 3464 runs late
Carrier accounts for 45% of the 6,481 delay minutes carriers reported here, and the remaining four split what is left.
- 45%Carrier
- 29%Late-arriving aircraft
- 17%National Airspace System
- 9%Extreme weather
The largest share of delay minutes, 45%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,910 of the 6,481 delay minutes reported here. The split is drawn from 6,481 delay minutes reported on YX 3464.
Cancellations run at 4.75%, against 1.89% nationally. That is about one flight in twenty 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
8.8% 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 an hour and a half, which a normal layover absorbs.
The same number turns up on two other city pairs in the data, including BDL to ORD (16) and BOS to EWR (1), but none flew often enough under YX 3464 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to PIT only.
One caution: this is a thin sample. 358 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 3464
For a booking, the cancellation rate is the figure to plan around on YX 3464: 4.75% of its 358 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
