Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3498, 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 3498 earns an A+. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs about 45 minutes. That rests on 294 flights, with a median arrival 9 minutes early.

These figures cover 294 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 3498 flies

YX 3498 flies ORD to CVG without a single fixed slot. Its most common scheduled departure was 07:10, used on 133 of 294 flights, with 07:30 (36 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 07:10 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 3498 runs level with that at 87.7%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

YX 3498 quarter by quarter

YX 3498 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.3% on time and its weakest Oct–Dec 2025 at 79.6%, a swing of 14 points on roughly 74 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 202590 flights93.3%
Oct–Dec 202554 flights79.6%
Jan–Mar 202682 flights85.2%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, YX 3498 did best on Tuesday at 95.3% on time and worst on Monday at 81.4%. Each day rests on about 42 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 3498 runs late

One category carries most of the weight here. National Airspace System accounts for 45% of the 1,623 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.

45%
Late-arriving aircraft
38%
Carrier
15%
Extreme weather
2%

38% 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 1,623 reported delay minutes here, that single category outweighs weather by 22 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 1,623 delay minutes reported on YX 3498.

Cancellations are rare at 0.34%, 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

Badly late arrivals are rare here: only 3.4% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

The same number turns up on eight other city pairs in the data, including CVG to EWR (18), GRB to ORD (10) and EWR to ATL (7), but none flew often enough under YX 3498 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to CVG only.

One caution: this is a thin sample. 294 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 3498

For a booking, YX 3498 has one of the better records a US domestic flight can show: 87.7% on time and 0.34% cancelled. That is a base rate, not a promise about any single day.
