Across the year
JetBlue on FLL to RDU through the year
December is the weak month at 41.8% on time, against 93.3% in September. 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. August was the busiest month here, with 93 flights.
Across the week, Wednesday is the strongest day at 83.8% on time and Friday the weakest at 60.8%, a spread of 23 points.

Worst days for JetBlue on FLL to RDU
The latest arrival of the period was on 18 December 2025, 5 hours 43 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The same cause led on five of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 18 December 2025 | 5 hours 43 minutes | Late-arriving aircraft |
| 2 August 2026 | 5 hours 5 minutes | Late-arriving aircraft |
| 19 July 2026 | 3 hours 59 minutes | Late-arriving aircraft |

Delay causes
Why JetBlue runs late on this route
Late-arriving aircraft accounts for 57% of the 14,000 delay minutes carriers reported here, and the remaining four split what is left.
- 57%Late-arriving aircraft
- 33%Carrier
- 8%National Airspace System
- 2%Extreme weather
- 0%Security
57% 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 29 to one. The split is drawn from 14,194 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 90.9% on time here.
Cancellations sit at 2.40% against a national 1.89%, which is ordinary. Diversions add another 0.15%.
Connections and stage length
What a delay here costs
12.7% 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 680 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 79.5% on time across 668 flights, 12 points above 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 12 points of difference.
One caution: this is a thin sample. 668 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 FLL to RDU
Put together: treat all of this as provisional. 668 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 67.6% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 651 completed flights over 12 months sit behind that.
