JetBlue on RSW to JFK carries a cancellation problem, not just a delay problem: 5.1% 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 807 flights, with a median arrival 5 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on RSW to JFK from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

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 50 points, against half a point between the best and worst carrier.
- 5am–8am214 flights90.6%
- 8am–11am95 flights79.3%
- 11am–2pm264 flights75.1%
- 2pm–5pm120 flights61.4%
- 5pm–8pm81 flights67.1%

Scale runs 30% to 95%.
The 8pm–5am window is where this operation falls apart: 40.6% on time, against 90.6% 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 11am–2pm window is the busiest, with 264 flights scheduled in it.
Across the year
JetBlue on RSW to JFK through the year

JetBlue on RSW to JFK often beats the schedule: 231 of 765 completed flights, 30%, arrived 15 minutes or more early. The 188 late arrivals split 52 under half an hour, 51 between 30 and 60 minutes, and 85 an hour or more.

Share of 765 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 167 departures that left 15 minutes late or more, only 19 made it up before arrival. In the other direction, 40 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 RSW to JFK
The latest arrival of the period was on 9 November 2025, 7 hours 57 minutes behind schedule; most of its delay minutes were filed as national airspace system delay. On three of the five worst days the largest share was filed as carrier-caused (crew, maintenance, fuelling, baggage).
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 9 November 2025 | 7 hours 57 minutes | National Airspace System |
| 14 February 2026 | 7 hours 23 minutes | Carrier |
| 22 August 2026 | 6 hours 34 minutes | Carrier |
| 16 February 2026 | 5 hours 54 minutes | Late-arriving aircraft |
| 4 July 2026 | 4 hours 37 minutes | Carrier |
Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 47% of the 15,000 delay minutes carriers reported here, and the remaining four split what is left.
- 47%Late-arriving aircraft
- 28%National Airspace System
- 25%Carrier
- 1%Extreme weather
- 0%Security
47% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 15,000 reported delay minutes here, that single category outweighs weather by 47 to one. The split is drawn from 15,075 reported delay minutes.
The practical consequence: the 5am–8am departure is the one that starts clean. Its aircraft has no earlier leg to be late from, which is exactly why that window shows 90.6% on time here.
Cancellations run at 5.08%, against 1.89% 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
11.1% 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.
The 1,074 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
The return leg runs 73.2% on time across 809 flights, within 2 points of this direction. The two legs are scored separately because they usually differ; on this city pair they happen not to.
One caution: this is a thin sample. 807 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 RSW to JFK
Put together: the delay figures matter less here than the 5.08% 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. 765 completed flights over 12 months sit behind that.
