Republic on PIT to JFK earns an A. Close to nine flights in ten arrive inside the 15-minute window the DOT uses to define an on-time arrival, which puts it 10 points better than the national rate of 77.6%. When something does go wrong the average delay runs a little over an hour. That rests on 1,310 flights, with a median arrival 11 minutes early.

Set against the rest of the country, Republic's PIT to JFK record is 10 points better than the US average of 77.6%. That gap is worth roughly 102 fewer late arrivals for every thousand flights.

Every carrier on PIT to JFK, 1,764 flights

These figures cover 1,310 flights between July 2025 and June 2026. The median arrival is 11 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 PIT to JFK

Republic flew 1,310 of the 1,764 flights on PIT to JFK, most of the route. Its 87.8% on time is about level with the route as a whole at 87.0%. Ranked by on-time rate it is first of two carriers on the route, where the range runs from Republic at 87.8% to JetBlue at 84.7%.

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.

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–8am481 flights93.5%
8am–11am253 flights90.2%
11am–2pm390 flights82.7%
2pm–5pm4 flights—
5pm–8pm137 flights76.2%
8pm–5am45 flights90.7%

Scale runs 70% to 100%. Rows with fewer than 30 flights show a dash.

Book the early departure. Flights leaving between 5am–8am arrive on time 93.5% of the time, against 76.2% for the evening window. That is 17 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 481 flights scheduled in it.

Across the year

Republic on PIT to JFK through the year

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

December is the weak month at 73.1% on time, against 93.5% 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 90.4% on time and Sunday the weakest at 83.1%. 7 points is a smaller lever than departure hour, but it is free.

Delay causes

Why Republic runs late on this route

Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 12,000 reported delay minutes.

Late-arriving aircraft
34%
National Airspace System
32%
Carrier
27%
Extreme weather
7%

34% 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 12,000 reported delay minutes here, that single category outweighs weather by 5 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 11,521 reported delay minutes.

32% 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 3,687 minutes out of 12,000, against a national NAS share of 21%.

Cancellations run at 2.52%, against 1.81% nationally. That is about one flight in 40 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

Badly late arrivals are rare here: only 4.7% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

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 5am–8am window matters as much as it does.

The return leg is a different operation and performs like one: it runs 78.5% on time across 1,310 flights, 9 points below 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 PIT to JFK

Put together: the calendar is the biggest lever here, not the carrier or the hour. August runs 93.5% on time and December 73.1%, a swing of 20 points. If the dates move at all, move them out of December before you think about anything else. 1,275 completed flights over 12 months sit behind that.
