Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on JAX to EWR sits in the middle of the pack with a C−. Close to three flights in four arrive on time by the DOT's definition, 3 points worse than the national rate of 77.6%. The late ones land close to two hours behind schedule. That rests on 200 flights, with a median arrival 11 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate Republic on JAX to EWR from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

These figures cover 200 flights between July 2025 and June 2026. Beyond the headline rate, 14.4% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.
Carrier by carrier
Republic against every carrier on JAX to EWR
Republic flew 200 of the 1,374 flights on JAX to EWR, about 15% of it. Its 74.6% on time is 5 points worse than the route as a whole, which runs 79.1%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from United at 79.9% to Republic at 74.6%.
Only one carrier clears this site's 365-flight floor here, so there is no comparison to draw. The table below is the full picture.

Departure window
When Republic runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 200 flights.
There are not enough flights in each departure window to split Republic's JAX to EWR record by time of day without the percentages moving on noise. The headline rate of 74.6% is the reliable figure here.

- Oct–Dec 202518 flights—

Scale runs 35% to 95%. Rows with fewer than 30 flights show a dash.
Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 74.6% on time across 200 flights.
Republic on JAX to EWR did not run the same all year. Its best quarter was Jan–Mar 2026 at 88.1% on time and its weakest Jul–Sep 2025 at 43.8%, a swing of 44 points on roughly 67 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.
Delay causes
Why Republic runs late on this route
One category carries most of the weight here. National Airspace System accounts for 43% of the 5,538 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.

- 26%Late-arriving aircraft
- 15%Extreme weather
- 15%Carrier
Extreme weather accounts for 15% 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 monthly strip above is the more useful view of the risk. The national share is 6%, so this operation carries roughly 2.4 times the usual weather exposure. The split is drawn from 5,538 reported delay minutes.
43% 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 2,403 minutes out of 5,538, against a national NAS share of 21%.
Cancellations run at 9.00%, against 1.81% 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 stage length
What a delay here costs
For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 14.4% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.
The 820 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 return leg is a different operation and performs like one: it runs 81.6% on time across 199 flights, 7 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 7 points of difference.
One caution: this is a thin sample. 200 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 Republic on JAX to EWR
Put together: the delay figures matter less here than the 9.00% cancellation rate. A late arrival costs you close to two hours; a cancelled flight costs you the day. Book the 5pm–8pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 181 completed flights over 12 months sit behind that.
