JetBlue on JAX to JFK carries a cancellation problem, not just a delay problem: 5.5% 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 891 flights, with a median arrival 7 minutes early.
The US average over the same twelve months is 77.3%, so there is little to separate JetBlue on JAX to JFK from the country as a whole. The variation that matters here is internal: which carrier, and what time of day.

Carrier by carrier
JetBlue against every carrier on JAX to JFK
JetBlue flew 891 of the 1,188 flights on JAX to JFK, most of the route. Its 77.2% on time is 3 points better than the route as a whole, which runs 74.2%. Ranked by on-time rate it is number two of three carriers on the route, where the range runs from Republic at 87.8% to Delta at 61.6%. Two of those carriers flew fewer than 365 flights here, so treat their positions as rough.
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 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 34 points, against half a point between the best and worst carrier.
- 5am–8am277 flights92.5%
- 8am–11am158 flights80.5%
- 11am–2pm103 flights82.2%
- 2pm–5pm25 flights—
- 5pm–8pm285 flights58.8%
- 8pm–5am43 flights63.4%
Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.
The 5pm–8pm window is where this operation falls apart: 58.8% on time, against 92.5% 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 5pm–8pm window is the busiest, with 285 flights scheduled in it.
Across the year
JetBlue on JAX to JFK through the year
December is the weak month at 67.9% on time, against 90.3% in May. 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. December was the busiest month here, with 92 flights.
Across the week, Tuesday is the strongest day at 84.3% on time and Sunday the weakest at 68.9%, a spread of 15 points.

The worst days
Worst days for JetBlue on JAX to JFK
The latest arrival of the period was on 7 June 2026, 14 hours 57 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on four of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 7 June 2026 | 14 hours 57 minutes | Late-arriving aircraft |
| 6 August 2026 | 6 hours 15 minutes | Late-arriving aircraft |
| 12 June 2026 | 5 hours 27 minutes | Carrier |
| 16 August 2026 | 4 hours 46 minutes | Late-arriving aircraft |
| 21 January 2026 | 4 hours 35 minutes | Late-arriving aircraft |
Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 52% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 52%Late-arriving aircraft
- 25%National Airspace System
- 19%Carrier
- 4%Extreme weather
- 0%Security
52% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 14,000 reported delay minutes here, that single category outweighs weather by 13 to one. The split is drawn from 13,736 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 5.50%, against 1.89% nationally. That is roughly 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
8.9% 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.
The 829 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 is a different operation and performs like one: it runs 73.4% on time across 891 flights, 4 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 4 points of difference.
One caution: this is a thin sample. 891 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 JAX to JFK
Put together: the delay figures matter less here than the 5.50% 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. 839 completed flights over 12 months sit behind that.
