These figures cover 258 flights between September 2025 and August 2026. The median arrival is 4 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.

Across the year
YX 3526 quarter by quarter
Quarter by quarter YX 3526 held fairly steady: 71.8% in Oct–Dec 2025, 80.0% in Jan–Mar 2026 and 73.9% in Apr–Jun 2026. A spread of 8 points is about what a sample of this size moves on its own, so the annual figure is a fair summary.
- Jul–Sep 202529 flights—
- Oct–Dec 202589 flights71.8%
- Jan–Mar 202690 flights80.0%

Share of 245 completed flights by arrival against schedule.
10 of 52 late departures made up the time and arrived on time, 19% of them. In the other direction, 17 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at IND.
The worst days
Worst days for YX 3526
The latest arrival of the period was on 30 December 2025, 11 hours 12 minutes behind schedule; most of its delay minutes were filed as extreme weather. The five worst days are spread across December, March, April and November, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 30 December 2025 | 11 hours 12 minutes | Extreme weather |
| 26 March 2026 | 10 hours 21 minutes | Carrier |
| 19 December 2025 | 10 hours 19 minutes | Late-arriving aircraft |

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 4,557 reported delay minutes.
- 39%Late-arriving aircraft
- 23%Carrier
- 22%Extreme weather
- 16%National Airspace System
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 3.7 times the usual weather exposure. The split is drawn from 4,557 delay minutes reported on YX 3526.
Cancellations run at 4.65%, against 1.89% nationally. That is about one flight in twenty 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
7.3% of arrivals land an hour or more late, close to the national 8.3%, so 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 five other city pairs in the data, including IAD to SDF (81), MSY to ORD (28) and ORD to GSP (11), 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. 258 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: 4.65% of its 258 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.
