Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3464, 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 3464 lands a B−, 2 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 351 flights, with a median arrival 3 minutes early.

These figures cover 351 flights between July 2025 and June 2026. The median arrival is 3 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 3464 flies

YX 3464 flies ORD to PIT without a single fixed slot. Its most common scheduled departure was 21:20, used on 91 of 351 flights, with 21:15 (87 flights) and 21:07 (68 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 21:20 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and YX 3464 runs 9 points better at 79.4%. 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 3464 quarter by quarter

Quarter by quarter YX 3464 held fairly steady: 80.5% in Jul–Sep 2025, 76.5% in Oct–Dec 2025, 79.5% in Jan–Mar 2026 and 81.2% in Apr–Jun 2026. A spread of 5 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jul–Sep 202584 flights80.5%
Oct–Dec 202588 flights76.5%
Jan–Mar 202688 flights79.5%

Scale runs 70% to 85%. Rows with fewer than 30 flights show a dash.

By weekday, YX 3464 did best on Wednesday at 85.1% on time and worst on Thursday at 69.4%. Each day rests on about 50 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 3464 runs late

One category carries most of the weight here. Carrier accounts for 49% of the 5,906 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.

Carrier
49%
Late-arriving aircraft
34%
National Airspace System
15%
Extreme weather
1%

34% 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 5,906 reported delay minutes here, that single category outweighs weather by 25 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 5,906 delay minutes reported on YX 3464.

Cancellations run at 4.56%, 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

7.8% 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 three other city pairs in the data, including BDL to ORD (16), DFW to EWR (3) and BOS to EWR (1), but none flew often enough under YX 3464 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to PIT only.

One caution: this is a thin sample. 351 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 3464

For a booking, the cancellation rate is the figure to plan around on YX 3464: 4.56% of its 351 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.
