Across the year
YX 3586 quarter by quarter
YX 3586 did not run the same all year. Its best quarter was Jan–Mar 2026 at 86.8% on time and its weakest Jul–Sep 2026 at 76.6%, a swing of 10 points on roughly 65 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.

- Oct–Dec 202570 flights79.1%
- Jan–Mar 202643 flights86.8%
- Apr–Jun 202682 flights82.5%

Scale runs 70% to 90%. Rows with fewer than 30 flights show a dash.
By weekday, YX 3586 did best on Friday at 90.0% on time and worst on Sunday at 65.7%. Each day rests on about 37 flights, so a gap of 24 points is worth noticing but could still narrow in another year.

| 6 June 2026 | 3 hours 50 minutes | Extreme weather |

Delay causes
Why YX 3586 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 3,817 reported delay minutes.
- 30%National Airspace System
- 26%Extreme weather
- 24%Late-arriving aircraft
- 21%Carrier
Extreme weather accounts for 26% 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 4.3 times the usual weather exposure. The split is drawn from 3,817 delay minutes reported on YX 3586.
Cancellations run at 8.46%, against 1.89% nationally. That is about one flight in twelve 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
8.0% 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 an hour and a half, which a normal layover absorbs.
The same number turns up on eleven other city pairs in the data, including EWR to CMH (32), ORD to GRR (22) and PHL to IAD (16), but none flew often enough under YX 3586 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to DTW only.
One caution: this is a thin sample. 260 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 3586
For a booking, the cancellation rate is the figure to plan around on YX 3586: 8.46% of its 260 scheduled flights did not operate. A late arrival costs an hour and a half, but a cancellation costs the day, so leave a later option open.
