These figures cover 271 flights between July 2025 and June 2026. Beyond the headline rate, 10.9% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When YX 4611 flies

YX 4611 flies JFK to PIT without a single fixed slot. Its most common scheduled departure was 19:40, used on 51 of 271 flights, with 18:59 (39 flights) and 17:20 (37 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 19:40 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and YX 4611 runs 6 points better at 73.8%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

YX 4611 quarter by quarter

Quarter by quarter YX 4611 held fairly steady: 72.5% in Jul–Sep 2025, 70.8% in Oct–Dec 2025, 80.4% in Jan–Mar 2026 and 72.5% in Apr–Jun 2026. A spread of 10 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, YX 4611 did best on Wednesday at 81.1% on time and worst on Sunday at 62.5%. Each day rests on about 39 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 4611 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 57% of the 5,754 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Extreme weather
4%

57% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,754 reported delay minutes here, that single category outweighs weather by 16 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,754 delay minutes reported on YX 4611.

Cancellations run at 8.12%, against 1.81% 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 10.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

The same number turns up on four other city pairs in the data, including ATL to LGA (38), ORD to LGA (26) and ORD to ALB (10), but none flew often enough under YX 4611 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to JFK to PIT only.

One caution: this is a thin sample. 271 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 4611

For a booking, the cancellation rate is the figure to plan around on YX 4611: 8.12% of its 271 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.
