Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3669, 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 3669 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 12 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 280 flights, with a median arrival 8 minutes early.

Set against the rest of the country, YX 3669's record is 12 points better than the US average of 77.6%. That gap is worth roughly 121 fewer late arrivals for every thousand flights.

These figures cover 280 flights between July 2025 and June 2026. The median arrival is 8 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 3669 flies

YX 3669 flies EWR to IND without a single fixed slot. Its most common scheduled departure was 09:41, used on 51 of 280 flights, with 09:15 (45 flights) and 09:34 (34 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 09:41 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 3669 runs 6 points better at 89.7%. 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 3669 next to EWR to IND

Across the year

YX 3669 quarter by quarter

YX 3669 did not run the same all year. Its best quarter was Apr–Jun 2026 at 96.4% on time and its weakest Oct–Dec 2025 at 85.7%, a swing of 11 points on roughly 70 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 3669 ranged from 82.5% on Monday to 92.7% on Wednesday. With about 40 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 3669 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 51% of the 2,160 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.

  • Late-arriving aircraft
    51%
  • National Airspace System
    26%
  • Carrier
    16%
  • Extreme weather
    6%

51% 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 2,160 reported delay minutes here, that single category outweighs weather by 8 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 2,160 delay minutes reported on YX 3669.

Cancellations run at 2.86%, against 1.81% nationally. That is roughly one flight in 30 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 3.3% 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 645 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.

The same number turns up on eight other city pairs in the data, including PWM to EWR (26), EWR to JAX (13) and IAD to SYR (10), but none flew often enough under YX 3669 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to IND only.

One caution: this is a thin sample. 280 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 3669

For a booking, the cancellation rate is the figure to plan around on YX 3669: 2.86% of its 280 scheduled flights did not operate. A late arrival costs a little over an hour, but a cancellation costs the day, so leave a later option open.
