Historical statistics for July 2025 to June 2026, not live status. For today’s YX 3718, 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 3718 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 a little over an hour. That rests on 278 flights, with a median arrival 14 minutes early.
Set against the rest of the country, YX 3718's record is 10 points better than the US average of 77.6%. That gap is worth roughly 100 fewer late arrivals for every thousand flights.

These figures cover 278 flights between July 2025 and June 2026. The median arrival is 14 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 3718 flies
YX 3718 flies GRR to EWR without a single fixed slot. Its most common scheduled departure was 06:00, used on 185 of 278 flights, with 06:15 (35 flights) and 06:45 (31 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.
A 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and YX 3718 runs level with that at 87.6%. 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 3718 next to GRR to EWR

Across the year
YX 3718 quarter by quarter
YX 3718 did not run the same all year. Its best quarter was Apr–Jun 2026 at 94.4% on time and its weakest Jan–Mar 2026 at 82.7%, a swing of 12 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.

Scale runs 75% to 100%. Rows with fewer than 30 flights show a dash.
By weekday, YX 3718 ranged from 84.2% on Sunday to 92.1% on Friday. With about 40 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.
Delay causes
Why YX 3718 runs late
One category carries most of the weight here. Carrier accounts for 46% of the 2,416 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.
- 46%Carrier
- 31%National Airspace System
- 23%Late-arriving aircraft
The largest share of delay minutes, 46%, 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 1,117 of the 2,416 delay minutes reported here. The split is drawn from 2,416 delay minutes reported on YX 3718.
Cancellations run at 3.96%, against 1.81% nationally. That is about one flight in 25 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 4.5% 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 605 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 five other city pairs in the data, including ORD to MSN (34), SDF to IAD (23) and IAD to BTV (4), but none flew often enough under YX 3718 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to GRR to EWR only.
One caution: this is a thin sample. 278 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 3718
For a booking, the cancellation rate is the figure to plan around on YX 3718: 3.96% of its 278 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.
