Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3523, 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 3523 lands a B+, level with the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 281 flights, with a median arrival 9 minutes early.

These figures cover 281 flights between July 2025 and June 2026. The median arrival is 9 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 3523 flies

YX 3523 flies ORD to RIC without a single fixed slot. Its most common scheduled departure was 14:48, used on 62 of 281 flights, with 14:15 (53 flights) and 14:02 (46 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 14:48 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and YX 3523 runs 6 points better at 78.1%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

YX 3523 quarter by quarter

Quarter by quarter YX 3523 held fairly steady: 77.9% in Jul–Sep 2025, 80.5% in Oct–Dec 2025, 72.6% in Jan–Mar 2026 and 81.1% in Apr–Jun 2026. A spread of 9 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jan–Mar 202664 flights72.6%

By weekday, YX 3523 ranged from 72.5% on Monday to 83.7% on Tuesday. With about 40 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 3523 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 4,403 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.

47%
National Airspace System
25%
Carrier
18%
Extreme weather
9%

47% 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 4,403 reported delay minutes here, that single category outweighs weather by 5 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 4,403 delay minutes reported on YX 3523.

Cancellations are rare at 0.71%, below the national 1.81% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.

Connections and routes

What a delay on this flight costs

7.9% 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 a little over an hour, which a normal layover absorbs.

The 642 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.

The same number turns up on seven other city pairs in the data, including IND to ORD (24), IND to EWR (21) and IAD to CVG (21), but none flew often enough under YX 3523 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to RIC only.

One caution: this is a thin sample. 281 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 3523
