Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3545, 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 3545 lands a B−, level with the national rate of 77.6%. Roughly one flight in four 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 340 flights, with a median arrival 9 minutes early.

These figures cover 340 flights between July 2025 and June 2026. Beyond the headline rate, 8.7% 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 3545 flies

YX 3545 flies EWR to CMH without a single fixed slot. Its most common scheduled departure was 16:59, used on 55 of 340 flights, with 17:30 (50 flights) and 17:28 (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 16:59 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and YX 3545 runs 5 points better at 77.6%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

YX 3545 quarter by quarter

YX 3545 did not run the same all year. Its best quarter was Jan–Mar 2026 at 83.5% on time and its weakest Jul–Sep 2025 at 65.1%, a swing of 18 points on roughly 85 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.

Jul–Sep 202592 flights65.1%
Oct–Dec 202572 flights82.6%
Jan–Mar 202685 flights83.5%
Apr–Jun 202691 flights80.7%

Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, YX 3545 ranged from 72.1% on Saturday to 82.2% on Monday. With about 49 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 3545 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 6,324 reported delay minutes.

Late-arriving aircraft
41%
Carrier
35%
National Airspace System
19%
Extreme weather
5%

41% 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 6,324 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 6,324 delay minutes reported on YX 3545.

Cancellations run at 5.29%, against 1.81% nationally. That is about 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

8.7% 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 an hour and a half, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including IAD to EYW (19), but none flew often enough under YX 3545 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to CMH only.

One caution: this is a thin sample. 340 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 3545

For a booking, the cancellation rate is the figure to plan around on YX 3545: 5.29% of its 340 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.
