Across the year
YX 3510 quarter by quarter
YX 3510 did not run the same all year. Its best quarter was Apr–Jun 2026 at 87.8% on time and its weakest Oct–Dec 2025 at 62.7%, a swing of 25 points on roughly 93 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 202585 flights62.7%
- Jan–Mar 202628 flights—
- Apr–Jun 202684 flights87.8%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, YX 3510 did best on Friday at 80.5% on time and worst on Thursday at 58.3%. Each day rests on about 40 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

The worst days
Worst days for YX 3510
The latest arrival of the period was on 6 August 2026, 13 hours 17 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 August 2026 | 13 hours 17 minutes | Carrier |
| 14 April 2026 | 5 hours 16 minutes | Extreme weather |
| 10 June 2026 | 4 hours 39 minutes | Late-arriving aircraft |

Delay causes
Why YX 3510 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 4,909 reported delay minutes.
- 39%National Airspace System
- 33%Late-arriving aircraft
- 21%Carrier
- 7%Extreme weather
39% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,913 minutes out of 4,909, against a national NAS share of 21%. The split is drawn from 4,909 delay minutes reported on YX 3510.
Cancellations run at 9.32%, against 1.89% nationally. That is about one flight in ten 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
8.7% 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 725 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.
The same number turns up on eight other city pairs in the data, including CHA to ORD (32), MCI to ORD (20) and EWR to CHS (7), but none flew often enough under YX 3510 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to MKE to EWR only.
One caution: this is a thin sample. 279 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 3510
For a booking, the cancellation rate is the figure to plan around on YX 3510: 9.32% of its 279 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.
