Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3526, 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 3526 lands a B−, about a point worse than the national rate of 77.6%. About one flight in four 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 271 flights, with a median arrival 5 minutes early.

These figures cover 271 flights between July 2025 and June 2026. The median arrival is 5 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 3526 flies

YX 3526 flies ORD to IND without a single fixed slot. Its most common scheduled departure was 21:30, used on 45 of 271 flights, with 21:13 (37 flights) and 21:10 (36 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 21:30 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and YX 3526 runs 6 points better at 76.7%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Against the route

YX 3526 next to ORD to IND

Across the year

YX 3526 quarter by quarter

YX 3526 did not run the same all year. Its best quarter was Jul–Sep 2025 at 83.3% on time and its weakest Oct–Dec 2025 at 71.8%, a swing of 12 points on roughly 68 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 202542 flights83.3%
Oct–Dec 202589 flights71.8%
Jan–Mar 202690 flights80.0%
Apr–Jun 202650 flights73.9%

Scale runs 65% to 90%. Rows with fewer than 30 flights show a dash.

By weekday, YX 3526 did best on Tuesday at 86.8% on time and worst on Friday at 67.6%. Each day rests on about 39 flights, so a gap of 19 points is worth noticing but could still narrow in another year.

Delay causes

Why YX 3526 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 4,587 reported delay minutes.

Late-arriving aircraft
39%
Carrier
23%
Extreme weather
22%
National Airspace System
16%

Extreme weather accounts for 22% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.5 times the usual weather exposure. The split is drawn from 4,587 delay minutes reported on YX 3526.

Cancellations run at 4.43%, against 1.81% nationally. That is roughly one flight in 25 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

7.0% 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 same number turns up on seven other city pairs in the data, including BDL to IAD (42), IAD to SDF (40) and MSY to ORD (28), but none flew often enough under YX 3526 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to ORD to IND only.

One caution: this is a thin sample. 271 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 3526

For a booking, the cancellation rate is the figure to plan around on YX 3526: 4.43% of its 271 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.
