Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on BOS to EWR carries a cancellation problem, not just a delay problem: 6.3% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, close to three flights in four arrive on time, worth a C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 1,187 flights, with a median arrival 7 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate Republic on BOS 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 1,187 flights between July 2025 and June 2026. Beyond the headline rate, 10.0% 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 BOS to EWR
Republic flew 1,187 of the 3,906 flights on BOS to EWR, about 30% of it. Its 73.7% on time is about level with the route as a whole at 74.9%. Ranked by on-time rate it is last of two carriers on the route, where the range runs from United at 75.5% to Republic at 73.7%.
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.

| United Airlines | 2,719 | 75.5% | 84 min | 3.46% | B− |

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 31 points, against half a point between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am344 flights92.8%
- 8am–11am24 flights—
- 11am–2pm386 flights67.0%
- 2pm–5pm58 flights61.5%
- 5pm–8pm364 flights63.6%
- 8pm–5am11 flights—
Scale runs 55% to 100%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 92.8% of the time, against 61.5% for the afternoon window. That is 31 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 11am–2pm window is the busiest, with 386 flights scheduled in it.
Across the year
Republic on BOS to EWR through the year
July is the worst month at 54.0% on time, 32 points below January, the best at 85.9%. 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. March was the busiest month here, with 118 flights.
Across the week, Monday is the strongest day at 77.4% on time and Saturday the weakest at 71.2%. 6 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 60% of the 20,000 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.
- 60%National Airspace System
- 20%Late-arriving aircraft
- 18%Carrier
- 2%Extreme weather
60% 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 12,000 minutes out of 20,000, against a national NAS share of 21%. The split is drawn from 20,011 reported delay minutes.
Cancellations run at 6.32%, against 1.81% nationally. That is about one flight in fifteen 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. 10.0% 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.
At 200 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 5am–8am window matters as much as it does.
The return leg runs 73.3% on time across 1,187 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 1,187 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 BOS to EWR
Put together: the delay figures matter less here than the 6.32% 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. 1,112 completed flights over 12 months sit behind that.
