Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on IND to EWR carries a cancellation problem, not just a delay problem: 3.7% 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 1,903 flights, with a median arrival 14 minutes early.
Set against the rest of the country, Republic's IND to EWR record is 6 points better than the US average of 77.6%. That gap is worth roughly 61 fewer late arrivals for every thousand flights.

These figures cover 1,903 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.
Carrier by carrier
Republic against every carrier on IND to EWR
Republic flew 1,903 of the 2,223 flights on IND to EWR, most of the route. Its 83.7% on time is about level with the route as a whole at 84.2%. Ranked by on-time rate it is last of three carriers on the route, where the range runs from United at 100.0% to Republic at 83.7%. 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 21 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.

- 8am–11am476 flights92.3%
- 11am–2pm357 flights82.9%

Scale runs 65% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 92.4% of the time, against 71.5% for the evening window. That is 21 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 476 flights scheduled in it.
Across the year
Republic on IND to EWR through the year
December is the weak month at 72.6% on time, against 92.5% in May. 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. May was the busiest month here, with 176 flights.
Across the week, Tuesday is the strongest day at 86.4% on time and Sunday the weakest at 81.2%. 5 points is a smaller lever than departure hour, but it is free.
Delay causes
Why Republic runs late on this route
One category carries most of the weight here. National Airspace System accounts for 58% of the 23,000 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.
- 58%National Airspace System
- 24%Late-arriving aircraft
- 16%Carrier
- 2%Extreme weather
58% 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 13,000 minutes out of 23,000, against a national NAS share of 21%. The split is drawn from 22,525 reported delay minutes.
Cancellations run at 3.73%, 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 stage length
What a delay here costs
5.7% 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 last a little over an hour, 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. 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 runs 83.5% on time across 1,904 flights, within half a point 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 1,903 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 IND to EWR
Put together: the delay figures matter less here than the 3.73% 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. 1,829 completed flights over 12 months sit behind that.
