Across the year
YX 3447 quarter by quarter
YX 3447 did not run the same all year. Its best quarter was Apr–Jun 2026 at 82.0% on time and its weakest Jul–Sep 2026 at 62.9%, a swing of 19 points on roughly 75 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.

7 of 51 late departures made up the time and arrived on time, 14% of them. In the other direction, 18 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.
The worst days
Worst days for YX 3447
The latest arrival of the period was on 6 June 2026, 14 hours 20 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 June 2026 | 14 hours 20 minutes | Late-arriving aircraft |
| 11 June 2026 | 5 hours 59 minutes | Extreme weather |
| 9 July 2026 | 5 hours 58 minutes | Late-arriving aircraft |

Delay causes
Why YX 3447 runs late
Late-arriving aircraft accounts for 57% of the 5,271 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 19%National Airspace System
- 12%Extreme weather
- 12%Carrier
Extreme weather accounts for 12% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.0 times the usual weather exposure. The split is drawn from 5,271 delay minutes reported on YX 3447.
Cancellations run at 5.00%, 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
9.5% 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 HHH to EWR (82), EWR to IND (57) and MSY to EWR (21), but none flew often enough under YX 3447 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. 300 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 3447
For a booking, the cancellation rate is the figure to plan around on YX 3447: 5.00% of its 300 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.
