Historical statistics for July 2025 to June 2026, not live status. For today’s YX 4592, 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 4592 lands a B−, 3 points better than the national rate of 77.6%. About one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 284 flights, with a median arrival 7 minutes early.

These figures cover 284 flights between July 2025 and June 2026. Beyond the headline rate, 8.1% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When YX 4592 flies

YX 4592 flies IND to JFK without a single fixed slot. Its most common scheduled departure was 12:33, used on 43 of 284 flights. 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 12:33 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and YX 4592 runs level with that at 80.5%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

YX 4592 quarter by quarter

Quarter by quarter YX 4592 held fairly steady: 82.0% in Jul–Sep 2025, 80.5% in Oct–Dec 2025, 79.0% in Jan–Mar 2026 and 79.5% in Apr–Jun 2026. A spread of 3 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.

Jan–Mar 202666 flights79.0%

By weekday, YX 4592 did best on Monday at 86.5% on time and worst on Tuesday at 72.5%. Each day rests on about 41 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 4592 runs late

One category carries most of the weight here. National Airspace System accounts for 45% of the 3,643 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.

45%
Late-arriving aircraft
39%
Carrier
10%
Extreme weather
5%

39% 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 3,643 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 3,643 delay minutes reported on YX 4592.

Cancellations run at 3.52%, against 1.81% nationally. That is about 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

8.1% 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 665 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 four other city pairs in the data, including LGA to ATL (38), JFK to IND (37) and LGA to PIT (25), but none flew often enough under YX 4592 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to IND to JFK only.

One caution: this is a thin sample. 284 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 4592

For a booking, the cancellation rate is the figure to plan around on YX 4592: 3.52% of its 284 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.
