Historical statistics for September 2025 to August 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: 6.2% of scheduled flights never operate, against 1.9% nationally. Of the ones that do fly, close to three flights in four 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 10 minutes early.
The US average over the same twelve months is 77.3%, 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.

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 16 points, against half a point between the best and worst carrier.
- 5am–8am—
- 8am–11am5 flights—
- 11am–2pm215 flights82.4%
- 2pm–5pm388 flights76.3%
- 5pm–8pm630 flights75.1%
- 8pm–5am72 flights66.7%
Scale runs 60% 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 66.7%. 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 630 flights scheduled in it.
Across the year
Republic on JFK to PIT through the year
August is the worst month at 62.7% on time, 23 points below April, the best at 85.7%. 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. July was the busiest month here, with 124 flights.
Across the week, Saturday is the strongest day at 80.8% on time and Sunday the weakest at 65.3%, a spread of 16 points.

Delay causes
Why Republic runs late on this route
Late-arriving aircraft accounts for 51% of the 24,000 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Late-arriving aircraft
- 26%National Airspace System
- 20%Carrier
- 4%Extreme weather
- 0%Security
51% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 24,000 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 24,056 reported delay minutes.
Cancellations run at 6.18%, against 1.89% 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
10.4% of arrivals land a full hour or more behind schedule, against 8.3% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
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 86.8% on time across 1,310 flights, 11 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 11 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 6.18% cancellation rate. A late arrival costs you an hour and a half; 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. 1,226 completed flights over 12 months sit behind that.
