Historical statistics for July 2025 to June 2026, not live status. For today’s flights, check with Republic Airways.
Republic on JFK to PIT carries a cancellation problem, not just a delay problem: 4.8% of scheduled flights never operate, against 1.8% nationally. Of the ones that do fly, about 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 1,310 flights, with a median arrival 11 minutes early.
The US average over the same twelve months is 77.6%, so there is little to separate Republic on JFK to PIT from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Every carrier on JFK to PIT, 1,764 flights
These figures cover 1,310 flights between July 2025 and June 2026. Beyond the headline rate, 8.9% 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 JFK to PIT
Republic flew 1,310 of the 1,764 flights on JFK to PIT, most of the route. Its 78.5% on time is 3 points better than the route as a whole, which runs 75.8%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Republic at 78.5% to JetBlue at 68.1%.
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.

| Republic Airways (this page) | 1,310 | 78.5% | 77 min | 4.81% | 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 17 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–8am—
- 8am–11am5 flights—
- 11am–2pm215 flights82.4%
- 2pm–5pm388 flights81.6%
- 5pm–8pm614 flights76.6%
- 8pm–5am88 flights65.7%
Scale runs 55% to 90%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 82.4% on time, ahead of 8pm–5am at 65.7%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 5pm–8pm window is the busiest, with 614 flights scheduled in it.
Across the year
Republic on JFK to PIT through the year
December is the weak month at 67.3% on time, against 86.8% in August. 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 124 flights.
Across the week, Saturday is the strongest day at 81.0% on time and Sunday the weakest at 69.8%. 11 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. Late-arriving aircraft accounts for 53% of the 21,000 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.
- 53%Late-arriving aircraft
- 24%National Airspace System
- 19%Carrier
- 4%Extreme weather
- 0%Security
53% 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 21,000 reported delay minutes here, that single category outweighs weather by 14 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 20,684 reported delay minutes.
Cancellations run at 4.81%, against 1.81% nationally. That is about 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.
Connections and stage length
What a delay here costs
8.9% 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.
At 340 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 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 87.8% on time across 1,310 flights, 9 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 9 points of difference.
The sample behind these figures is 1,310 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 JFK to PIT
Put together: the delay figures matter less here than the 4.81% cancellation rate. A late arrival costs you a little over an hour; a cancelled flight costs you the day. Book the 11am–2pm departure so there is still a schedule behind you if it goes wrong, and treat a same-day connection as optimistic. 1,244 completed flights over 12 months sit behind that.
