Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3477, 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 3477 lands a B−, about a point 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 about an hour on average. That is a workable record, not a spotless one. That rests on 306 flights, with a median arrival 17 minutes early.

These figures cover 306 flights between July 2025 and June 2026. The median arrival is 17 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 3477 flies

YX 3477 flies EWR to PIT without a single fixed slot. Its most common scheduled departure was 21:59, used on 157 of 306 flights, with 21:50 (40 flights) and 21:46 (32 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

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

A 21:59 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and YX 3477 runs 8 points better at 78.9%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

Across the year

YX 3477 quarter by quarter

YX 3477 did not run the same all year. Its best quarter was Jan–Mar 2026 at 85.7% on time and its weakest Jul–Sep 2025 at 71.8%, a swing of 14 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.

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, YX 3477 did best on Saturday at 85.7% on time and worst on Wednesday at 68.4%. 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 3477 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 4,061 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.

  • Late-arriving aircraft
    62%
  • Carrier
    22%
  • National Airspace System
    12%
  • Extreme weather
    5%

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 4,061 reported delay minutes here, that single category outweighs weather by 14 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 4,061 delay minutes reported on YX 3477.

Cancellations run at 7.19%, against 1.81% nationally. That is about 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

6.7% 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 eight other city pairs in the data, including RDU to EWR (53), STL to EWR (35) and ORD to ROC (31), but none flew often enough under YX 3477 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. 306 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 3477

For a booking, the cancellation rate is the figure to plan around on YX 3477: 7.19% of its 306 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
