Republic on JAX to EWR lands a B−, 4 points better than the national rate of 77.3%. About one flight in five arrives 15 minutes late or worse, and those flights are late by about 2.3 hours on average. That rests on 162 flights, with a median arrival 12 minutes early.
The US average over the same twelve months is 77.3%, 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.

Departure window
When Republic runs best on this route

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 81.1% is the reliable figure here.

Delay causes
Why Republic runs late on this route
National Airspace System accounts for 53% of the 3,877 delay minutes carriers reported here, and the remaining four split what is left.
- 53%National Airspace System
- 24%Carrier
- 21%Late-arriving aircraft
- 3%Extreme weather
53% 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 2,049 minutes out of 3,877, against a national NAS share of 21%. The split is drawn from 3,877 reported delay minutes.
Cancellations run at 8.02%, against 1.89% 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
10.1% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection 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.
The return leg is a different operation and performs like one: it runs 86.6% on time across 162 flights, 6 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 6 points of difference.
One caution: this is a thin sample. 162 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 8.02% cancellation rate. A late arrival costs you about 2.3 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. 148 completed flights over 12 months sit behind that.
