Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4701, 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 4701 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 362 flights, with a median arrival 11 minutes early.

Set against the rest of the country, YX 4701's record is 10 points better than the US average of 77.6%. That gap is worth roughly 100 fewer late arrivals for every thousand flights.

These figures cover 362 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 4701 flies

YX 4701 flies DCA to IND without a single fixed slot. Its most common scheduled departure was 10:30, used on 76 of 362 flights, with 10:00 (57 flights) and 09:59 (54 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

  • Departs 10:0057 flights15.7%

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 10:30 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 4701 runs 4 points better at 87.6%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

By weekday, YX 4701 ranged from 82.0% on Monday to 92.2% on Tuesday. With about 52 flights behind each day, a spread of 10 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why YX 4701 runs late

One category carries most of the weight here. Carrier accounts for 43% of the 2,929 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
    43%
  • Late-arriving aircraft
    42%
  • National Airspace System
    14%
  • Extreme weather
    2%

42% 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 2,929 reported delay minutes here, that single category outweighs weather by 28 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 2,929 delay minutes reported on YX 4701.

Cancellations sit at 1.66% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.3% 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 about an hour, which a normal layover absorbs.

The 500 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.

Every one of the 362 flights under YX 4701 in the data flew DCA to IND. The number was not reused on any other city pair, which makes this a clean record of one route.

One caution: this is a thin sample. 362 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 4701

For a booking, read YX 4701 as 87.6% on time with 1.66% cancelled over 362 flights. Those are rates from the past twelve months, not a forecast for any particular day.
