Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4716, 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 4716 earns an A. More than four flights in five arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 8 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 362 flights, with a median arrival 10 minutes early.

These figures cover 362 flights between July 2025 and June 2026. The median arrival is 10 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 4716 flies

YX 4716 flies IND to BOS without a single fixed slot. Its most common scheduled departure was 07:00, used on 132 of 362 flights, with 10:30 (47 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 4716 runs 4 points worse at 85.8%. 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 4716 quarter by quarter

YX 4716 did not run the same all year. Its best quarter was Apr–Jun 2026 at 92.2% on time and its weakest Jul–Sep 2025 at 76.1%, a swing of 16 points on roughly 91 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 4716 ranged from 80.8% on Tuesday to 90.4% on Wednesday. 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 4716 runs late

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 3,522 reported delay minutes.

National Airspace System
36%
Carrier
35%
Late-arriving aircraft
19%
Extreme weather
8%
Security
1%

The largest share of delay minutes, 35%, 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 1,249 of the 3,522 delay minutes reported here. The split is drawn from 3,522 delay minutes reported on YX 4716.

Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

6.7% 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 818 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 4716 in the data flew IND to BOS. 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 4716

For a booking, YX 4716 has one of the better records a US domestic flight can show: 85.8% on time and 1.10% cancelled. That is a base rate, not a promise about any single day.
