Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3697, 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 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 77.6%. When something does go wrong the average delay runs about 50 minutes. That rests on 309 flights, with a median arrival 11 minutes early.
Set against the rest of the country, YX 3697's record is 10 points better than the US average of 77.6%. That gap is worth roughly 104 fewer late arrivals for every thousand flights.

These figures cover 309 flights between July 2025 and June 2026. The median arrival is 11 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 3697 flies
YX 3697 flies EWR to MKE without a single fixed slot. Its most common scheduled departure was 09:00, used on 57 of 309 flights, with 08:30 (53 flights) and 08:42 (41 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.
- Departs 09:0057 flights18.4%
- Departs 08:3053 flights17.2%
- Departs 08:4241 flights13.3%
Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.
Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 09:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and YX 3697 runs 4 points better at 88.0%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.
Against the route
YX 3697 next to EWR to MKE

Across the year
YX 3697 quarter by quarter
YX 3697 did not run the same all year. Its best quarter was Jul–Sep 2025 at 97.5% on time and its weakest Oct–Dec 2025 at 79.3%, a swing of 18 points on roughly 77 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 202540 flights97.5%
- Oct–Dec 202589 flights79.3%
- Jan–Mar 202690 flights89.3%
- Apr–Jun 202690 flights91.1%
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, YX 3697 did best on Wednesday at 95.6% on time and worst on Sunday at 77.3%. Each day rests on about 44 flights, so a gap of 18 points is worth noticing but could still narrow in another year.
Delay causes
Why YX 3697 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 1,805 reported delay minutes.
- 41%Carrier
- 40%National Airspace System
- 19%Late-arriving aircraft
The largest share of delay minutes, 41%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 746 of the 1,805 delay minutes reported here. The split is drawn from 1,805 delay minutes reported on YX 3697.
Cancellations sit at 2.27% against a national 1.81%, which is ordinary. Diversions add another 0.32%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 3.0% land an hour or more behind schedule, against 8.1% 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. It is also long enough that the aircraft usually flies three or four legs a day rather than six, which slows how fast delay compounds.
The same number turns up on three other city pairs in the data, including CHS to EWR (49), EWR to PIT (14) and 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. 309 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
