Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4419, 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 4419 lands a B−, 5 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by about an hour on average. That is a workable record, not a spotless one. That rests on 267 flights, with a median arrival 10 minutes early.

Set against the rest of the country, YX 4419's record is 5 points better than the US average of 77.6%. That gap is worth roughly 49 fewer late arrivals for every thousand flights.

These figures cover 267 flights between July 2025 and June 2026. The median arrival is 10 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Schedule

When YX 4419 flies

YX 4419 flies GSO to LGA without a single fixed slot. Its most common scheduled departure was 10:52, used on 45 of 267 flights, with 11:03 (32 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 10:52 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 4419 runs level with that at 82.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

YX 4419 quarter by quarter

YX 4419 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.0% on time and its weakest Oct–Dec 2025 at 74.4%, a swing of 19 points on roughly 89 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.

By weekday, YX 4419 did best on Sunday at 89.5% on time and worst on Thursday at 76.3%. Each day rests on about 38 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 4419 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 2,856 reported delay minutes.

Late-arriving aircraft
42%
Extreme weather
24%
National Airspace System
18%
Carrier
16%

Extreme weather accounts for 24% 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 3.9 times the usual weather exposure. The split is drawn from 2,856 delay minutes reported on YX 4419.

Cancellations run at 5.62%, against 1.81% nationally. That is roughly 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

5.2% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last about an hour, which a normal layover absorbs.

The same number turns up on four other city pairs in the data, including LGA to GSO (233), CMH to PHL (44) and PHL to CMH (44), but none flew often enough under YX 4419 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to GSO to LGA only.

One caution: this is a thin sample. 267 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 4419

For a booking, the cancellation rate is the figure to plan around on YX 4419: 5.62% of its 267 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
