Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4700, 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 4700 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 an hour. That rests on 274 flights, with a median arrival 6 minutes early.

Set against the rest of the country, YX 4700's record is 10 points better than the US average of 77.6%. That gap is worth roughly 101 fewer late arrivals for every thousand flights.

These figures cover 274 flights between July 2025 and June 2026. The median arrival is 6 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 4700 flies

YX 4700 flies DCA to CMH without a single fixed slot. Its most common scheduled departure was 10:00, used on 129 of 274 flights, with 10:02 (45 flights) and 10:10 (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 10:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 4700 runs 4 points better 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.

Against the route

YX 4700 next to DCA to CMH

Republic flew 970 flights on the same city pair under all its flight numbers, including this one, and those ran 80.7% on time. Across its whole network Republic Airways managed 78.5%, which this flight beats by 9 points.

Across the year

YX 4700 quarter by quarter

YX 4700 did not run the same all year. Its best quarter was Jul–Sep 2025 at 94.6% on time and its weakest Jan–Mar 2026 at 77.6%, a swing of 17 points on roughly 69 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 flights94.6%

Jan–Mar 202661 flights77.6%

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

By weekday, YX 4700 did best on Wednesday at 92.9% on time and worst on Saturday at 75.8%. Each day rests on about 39 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 4700 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 62% of the 1,916 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.

Extreme weather
2%

62% 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 1,916 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 1,916 delay minutes reported on YX 4700.

Cancellations sit at 2.19% 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 1.9% 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 CMH to DCA (230), RDU to DCA (35) and DCA to RDU (35), but none flew often enough under YX 4700 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to DCA to CMH only.

One caution: this is a thin sample. 274 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 4700

For a booking, read YX 4700 as 87.7% on time with 2.19% cancelled over 274 flights. Those are rates from the past twelve months, not a forecast for any particular day.
