Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3447, 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 3447 lands a B−, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by an hour and a half on average. That is a workable record, not a spotless one. That rests on 261 flights, with a median arrival 15 minutes early.

These figures cover 261 flights between July 2025 and June 2026. The median arrival is 15 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 3447 flies

YX 3447 flies EWR to PIT without a single fixed slot. Its most common scheduled departure was 17:29, used on 123 of 261 flights, with 18:15 (31 flights) and 17:40 (30 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 17:29 departure sits in the 5pm–8pm window. Across every US flight scheduled in that window the on-time rate is 68.2%, and YX 3447 runs 12 points better at 80.3%. 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 3447 quarter by quarter

Quarter by quarter YX 3447 held fairly steady: 79.7% in Oct–Dec 2025, 78.8% in Jan–Mar 2026 and 82.0% in Apr–Jun 2026. A spread of 3 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

By weekday, YX 3447 ranged from 75.7% on Friday to 86.5% on Tuesday. With about 37 flights behind each day, a spread of 11 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 3447 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 4,044 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.

62%
National Airspace System
17%
Carrier
13%
Extreme weather
8%

62% 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 4,044 reported delay minutes here, that single category outweighs weather by 8 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 4,044 delay minutes reported on YX 3447.

Cancellations run at 4.21%, against 1.81% nationally. That is about one flight in 25 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

7.6% 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 an hour and a half, which a normal layover absorbs.

The same number turns up on nine other city pairs in the data, including HHH to EWR (41), EWR to IND (36) and IAD to BTV (31), 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. 261 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: 4.21% of its 261 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.
