JetBlue on JFK to RSW carries a cancellation problem, not just a delay problem: 4.8% 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 C− overall. The punctuality figure counts only flights that actually departed, so it flatters an operation that cancels this often. That rests on 809 flights, with a median arrival 5 minutes early.
The national on-time rate over the same period is 77.3%, so JetBlue on JFK to RSW runs 4 points behind the country as a whole. Across a thousand flights that is about 41 extra late arrivals.

Share of 764 completed flights by arrival against schedule.
49 of 212 late departures made up the time and arrived on time, 23% of them. In the other direction, 42 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 RSW.
The worst days
Worst days for JetBlue on JFK to RSW
The latest arrival of the period was on 3 August 2026, 5 hours 27 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across August, July, January and December, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 3 August 2026 | 5 hours 27 minutes | Late-arriving aircraft |
| 21 July 2026 | 4 hours 37 minutes | National Airspace System |
| 7 July 2026 | 4 hours 12 minutes | Carrier |
| 26 January 2026 | 4 hours 6 minutes | Extreme weather |
| 25 December 2025 | 3 hours 47 minutes | Late-arriving aircraft |
Delay causes
Why JetBlue 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 15,000 reported delay minutes.
- 42%Late-arriving aircraft
- 33%Carrier
- 21%National Airspace System
- 3%Extreme weather
- 0%Security
42% 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 13 to one. The split is drawn from 15,320 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 92.5% on time here.
Cancellations run at 4.82%, 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
12.0% 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 75.4% on time across 807 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. 809 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 JFK to RSW
Put together: the delay figures matter less here than the 4.82% 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. 764 completed flights over 12 months sit behind that.
