Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4410, check with Republic Airways. Republic Airways flies under contract for larger airlines, so a ticket for this flight may show a different airline code and number.

YX 4410 draws a C−. About one flight in three arrives at least 15 minutes late, and the typical late arrival is a little over an hour behind schedule. Build slack into anything you connect to. That rests on 308 flights, with a median arrival 2 minutes early.

The national on-time rate over the same period is 77.6%, so YX 4410 runs 10 points behind the country as a whole. Across a thousand flights that is about 97 extra late arrivals.

These figures cover 308 flights between July 2025 and June 2026. Beyond the headline rate, 16.2% 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 4410 flies

YX 4410 flies LGA to PIT without a single fixed slot. Its most common scheduled departure was 18:29, used on 67 of 308 flights, with 18:00 (53 flights) and 18:30 (39 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 18:29 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and YX 4410 runs level with that at 67.9%. 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 4410 quarter by quarter

YX 4410 did not run the same all year. Its best quarter was Apr–Jun 2026 at 78.4% on time and its weakest Oct–Dec 2025 at 60.0%, a swing of 18 points on roughly 77 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.

Jan–Mar 202678 flights71.2%

Scale runs 50% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, YX 4410 did best on Monday at 78.7% on time and worst on Sunday at 62.2%. Each day rests on about 44 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 4410 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 63% of the 7,526 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.

63% 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 7,526 reported delay minutes here, that single category outweighs weather by 9 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 7,526 delay minutes reported on YX 4410.

Cancellations run at 5.84%, against 1.81% nationally. That is roughly 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

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 16.2% 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 one other city pair in the data, including 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. 308 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: 5.84% of its 308 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
