YX 3697 earns an A−. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.3%. When something does go wrong the average delay runs about an hour. That rests on 358 flights, with a median arrival 10 minutes early.
Set against the rest of the country, YX 3697's record is 10 points better than the US average of 77.3%. That gap is worth roughly 97 fewer late arrivals for every thousand flights.

These figures cover 358 flights between September 2025 and August 2026. The median arrival is 10 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 3697 quarter by quarter
YX 3697 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.1% on time and its weakest Oct–Dec 2025 at 79.3%, a swing of 12 points on roughly 90 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 202527 flights—
- Oct–Dec 202589 flights79.3%
- Jan–Mar 202690 flights89.3%
- Apr–Jun 202690 flights91.1%
- Jul–Sep 202662 flights84.5%
Scale runs 70% to 95%. Rows with fewer than 30 flights show a dash.
By weekday, YX 3697 did best on Wednesday at 92.3% on time and worst on Sunday at 78.4%. Each day rests on about 51 flights, so a gap of 14 points is worth noticing but could still narrow in another year.

Share of 346 completed flights by arrival against schedule.
5 of 24 late departures made up the time and arrived on time, 21% of them. In the other direction, 26 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 MKE.

Delay causes
Why YX 3697 runs late
Carrier accounts for 44% of the 2,820 delay minutes carriers reported here, and the remaining four split what is left.
- 44%Carrier
- 33%National Airspace System
- 23%Late-arriving aircraft
The largest share of delay minutes, 44%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 1,245 of the 2,820 delay minutes reported here. The split is drawn from 2,820 delay minutes reported on YX 3697.
Cancellations run at 3.07%, against 1.89% nationally. That is roughly 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
Badly late arrivals are rare here: only 3.8% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
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 one other city pair in the data, including EWR to ATL (1), but none flew often enough under YX 3697 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to EWR to MKE only.
One caution: this is a thin sample. 358 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 3697
For a booking, the cancellation rate is the figure to plan around on YX 3697: 3.07% of its 358 scheduled flights did not operate. A late arrival costs about an hour, but a cancellation costs the day, so leave a later option open.
