Republic on EWR to IND carries a cancellation problem, not just a delay problem: 4.3% of scheduled flights never operate, against 1.9% 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 1,948 flights, with a median arrival 12 minutes early.

Set against the rest of the country, Republic's EWR to IND record is 6 points better than the US average of 77.3%. That gap is worth roughly 61 fewer late arrivals for every thousand flights.

These figures cover 1,948 flights between September 2025 and August 2026. The median arrival is 12 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.

Carrier by carrier

Republic against every carrier on EWR to IND

Republic flew 1,948 of the 2,204 flights on EWR to IND, most of the route. Its 83.4% on time is 2 points better than the route as a whole, which runs 81.7%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from United at 100.0% to Spirit at 68.8%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.

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 matters more here than the choice of carrier. The gap between the best and worst window is 20 points, against half a point between the best and worst carrier.

5am–8am195 flights89.2%
8am–11am318 flights87.3%
11am–2pm350 flights85.9%
2pm–5pm343 flights84.1%
5pm–8pm519 flights82.1%
8pm–5am223 flights69.3%

Scale runs 60% to 95%.

Book the early departure. Flights leaving between 5am–8am arrive on time 89.2% of the time, against 69.3% for the overnight window. That is 20 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5pm–8pm window is the busiest, with 519 flights scheduled in it.

Across the year

Republic on EWR to IND through the year

Darker means more delays. Figures are on-time percentages.April best, December worst

December is the weak month at 73.5% on time, against 96.0% in April. Winter delays cluster: a single storm system can account for most of a month's shortfall, so an average December hides both very good weeks and genuinely unflyable days. July was the busiest month here, with 180 flights.

Across the week, Saturday is the strongest day at 85.7% on time and Monday the weakest at 80.3%, a spread of 5 points.

Delay causes

Why Republic runs late on this route

Late-arriving aircraft accounts for 45% of the 26,000 delay minutes carriers reported here, and the remaining four split what is left.

Late-arriving aircraft
45%
National Airspace System
22%
Carrier
21%
Extreme weather
12%

Extreme weather accounts for 12% 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 1.9 times the usual weather exposure. The split is drawn from 25,532 reported delay minutes.

45% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 26,000 reported delay minutes here, that single category outweighs weather by 4 to one.

Cancellations run at 4.26%, against 1.89% 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 stage length

What a delay here costs

7.3% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last an hour and a half, which a normal layover absorbs.

The 645 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 runs 85.0% on time across 1,947 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.

The sample behind these figures is 1,948 flights, enough that the headline rate is stable to within roughly a point. The hour-block and month splits divide that further, so read the thinner bars with more caution than the headline.

What to do with this

Booking Republic on EWR to IND

Put together: the delay figures matter less here than the 4.26% cancellation rate. A late arrival costs you an hour and a half; 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. 1,861 completed flights over 12 months sit behind that.
