Share of 290 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 85 departures that left 15 minutes late or more, only 10 made it up before arrival. In the other direction, 21 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at PIT.

Delay causes
Why YX 4410 runs late
Late-arriving aircraft accounts for 63% of the 7,995 delay minutes carriers reported here, and the remaining four split what is left.
- 63%Late-arriving aircraft
- 16%National Airspace System
- 12%Carrier
- 9%Extreme weather
- 0%Security
63% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 7,995 reported delay minutes here, that single category outweighs weather by 7 to one. The split is drawn from 7,995 delay minutes reported on YX 4410.
Cancellations run at 7.03%, 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
16.9% 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 three other city pairs in the data, including GSP to MIA (5), MIA to GSP (5) and DCA to CLE (4), but none flew often enough under YX 4410 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to LGA to PIT only.
One caution: this is a thin sample. 313 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 4410
For a booking, the cancellation rate is the figure to plan around on YX 4410: 7.03% of its 313 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.
