These figures cover 454 flights between September 2025 and August 2026. The median arrival is 7 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.

Departure window
When JetBlue runs best on this route
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 22 points, against half a point between the best and worst carrier.

- 8am–11am4 flights—

- 5pm–8pm79 flights64.9%

Scale runs 55% to 95%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 64.9% on time, against 87.2% for the 5am–8am slot. By evening the aircraft flying these rotations have absorbed a full day of small delays and there is no slack left to recover in. The 5am–8am window is the busiest, with 365 flights scheduled in it.

Monthly volumes are too low here to break the year into twelve reliable readings. What the twelve-month total says is 83.3% on time across 454 flights.
JetBlue on PIT to JFK did not run the same all year. Its best quarter was Apr–Jun 2026 at 90.0% on time and its weakest Jul–Sep 2026 at 77.1%, a swing of 13 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.
Across the week, Wednesday is the strongest day at 90.6% on time and Sunday the weakest at 75.9%, a spread of 15 points.

Share of 420 completed flights by arrival against schedule.
9 of 53 late departures made up the time and arrived on time, 17% of them. In the other direction, 26 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at JFK.
The worst days
Worst days for JetBlue on PIT to JFK
The latest arrival of the period was on 2 April 2026, 7 hours 8 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). Three of the five worst days fell in November 2025.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 2 April 2026 | 7 hours 8 minutes | Carrier |
| 29 November 2025 | 5 hours 44 minutes | Late-arriving aircraft |
| 11 November 2025 | 4 hours 40 minutes | Carrier |
| 27 June 2026 | 4 hours 20 minutes | Carrier |

Delay causes
Why JetBlue runs late on this route
Carrier accounts for 47% of the 5,707 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Carrier
- 33%National Airspace System
- 18%Late-arriving aircraft
- 1%Extreme weather
- 0%Security
The largest share of delay minutes, 47%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 2,710 of the 5,707 delay minutes reported here. The split is drawn from 5,707 reported delay minutes.
33% 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 1,892 minutes out of 5,707, against a national NAS share of 21%.
Cancellations run at 7.49%, against 1.89% nationally. That is roughly one flight in twelve 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
6.2% of arrivals land an hour or more late, close to the national 8.3%, so 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 5am–8am window matters as much as it does.
The return leg is a different operation and performs like one: it runs 66.2% on time across 454 flights, 17 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 17 points of difference.
One caution: this is a thin sample. 454 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking JetBlue on PIT to JFK
Put together: the delay figures matter less here than the 7.49% 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. 420 completed flights over 12 months sit behind that.
