Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3430, 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 3430 earns an A. Nearly every flight arrives inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 17 points better than the national rate of 77.6%. When something does go wrong the average delay runs roughly 45 minutes. That rests on 321 flights, with a median arrival 11 minutes early.

These figures cover 321 flights between July 2025 and June 2026. The median arrival is 11 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 3430 flies

YX 3430 flies CMH to IAD without a single fixed slot. Its most common scheduled departure was 06:00, used on 177 of 321 flights, with 06:10 (121 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 3430 runs 5 points better at 94.6%. 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 3430 quarter by quarter

YX 3430 did not run the same all year. Its best quarter was Jan–Mar 2026 at 98.8% on time and its weakest Oct–Dec 2025 at 88.0%, a swing of 11 points on roughly 80 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.

By weekday, YX 3430 ranged from 90.9% on Sunday to 97.8% on Thursday. With about 46 flights behind each day, a spread of 7 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 3430 runs late

One category carries most of the weight here. Carrier accounts for 77% of the 739 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
77%
National Airspace System
23%

The largest share of delay minutes, 77%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 567 of the 739 delay minutes reported here. The split is drawn from 739 delay minutes reported on YX 3430.

Cancellations sit at 1.25% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 1.3% 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 seven other city pairs in the data, including BDL to IAD (24), IAD to LGA (18) and BUF to IAD (15), but none flew often enough under YX 3430 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to CMH to IAD only.

One caution: this is a thin sample. 321 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 3430

For a booking, YX 3430 has one of the better records a US domestic flight can show: 94.6% on time and 1.25% cancelled. That is a base rate, not a promise about any single day.
