Republic Airways at Newark carries a cancellation problem, not just a delay problem: 4.6% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, more than four flights in five arrive on time, worth a B− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 23,806 flights, of which Republic Airways flew 23,806 at 83.3% on time.
Measured against the airport rather than the country, Republic Airways runs 6 points ahead of the 77.7% weighted average across all carriers at EWR. That is the comparison worth making: every operator here works the same runways, the same airspace and the same weather.

#1
Of 10 carriers clearing the floor at EWR
These figures cover 24,000 flights between July 2025 and June 2026. The median arrival is 13 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.
Against the competition
Every carrier at EWR, ranked
The choice of carrier is not cosmetic here. Republic Airways arrives on time 83.3% of the time; Frontier Airlines manages 68.5%. Sample sizes sit next to every figure, because a two-point gap across 1,180 flights means less than a ten-point one.

Spirit Airlines cancels 6.6% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.
Route by route
Where Republic Airways flies from EWR
Republic Airways operates 25 routes out of EWR with enough volume to report. Route records inside one carrier at one airport still spread widely, because a short shuttle and a transcontinental have very different exposure to a late inbound.

Departure window
Best time of day for this operation
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against 15 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am779 flights93.6%
- 8am–11am6,107 flights88.5%
- 11am–2pm2,903 flights87.2%
- 2pm–5pm5,758 flights81.3%
- 5pm–8pm3,744 flights78.7%
- 8pm–5am4,515 flights78.0%
Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 93.6% of the time, against 78.0% for the overnight window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 8am–11am window is the busiest, with 6,107 flights scheduled in it.
Across the year
Seasonal pattern
July is the worst month at 72.2% on time, 20 points below May, the best at 91.8%. Summer afternoon convection and peak-season schedules land on the same weeks every year, so this is a pattern you can book around rather than a run of bad luck. May was the busiest month here, with 2,453 flights.
Delay causes
What holds this operation up
- 44%Late-arriving aircraft
- 25%National Airspace System
- 23%Carrier
- 8%Extreme weather
44% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 266,000 reported delay minutes here, that single category outweighs weather by 6 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 266,394 reported delay minutes.
Cancellations run at 4.62%, against 1.81% nationally. That is roughly one flight in twenty 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.
6.2% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route are the a little over an hour kind, which a normal layover absorbs.
23,806 flights sit behind these numbers, which is a large enough sample that the headline rate is not moving on noise. Where a sub-group falls below 30 flights the site shows a dash instead of a percentage.
Put together: the delay figures matter less here than the 4.62% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 5am–8am departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 22,663 completed flights over 12 months sit behind that.
Common questions
Republic Airways at EWR
How often is Republic Airways at EWR delayed?
About one flight in six arrive at least 15 minutes late, which is the Department of Transportation's definition of a delayed arrival. That works out to 16.7% of the 23,806 flights in this analysis, against 22.4% nationally. Delayed flights are late by a little over an hour on average.
Which airline is most reliable on Republic Airways at EWR?
Republic Airways leads at 83.3% on time across 23,806 flights. Frontier Airlines is at the other end on 68.5%, a gap of 15 points. Sample size matters as much as the percentage: a rate built from a few hundred flights moves around far more than one built from ten thousand.
What time of day has the fewest delays on Republic Airways at EWR?
The 5am–8am departure window is the strongest at 93.6% on time. The 8pm–5am window is the weakest at 78.0%, 16 points behind. Later departures inherit delays from earlier flights the same aircraft has already flown, which is why the curve slopes the way it does.
How bad are July delays on Republic Airways at EWR?
July is the weakest month at 72.2% on time, compared with 91.8% in May. Across the year that is 20 points between the best and worst months. Moving flexible dates out of that month is one of the few things that reliably helps.
