How B6700 performs
1,025 operations, July 2023 – July 2026.
B6700 arrived on time 76.3% of the time, against 77.5% for all LAX → FLL flights, so this departure is 1.2 percentage points worse than the route as a whole. Against JetBlue’s own flights on this route it is 2.8 points worse.

Why B6700 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding and fueling, all within the carrier’s control
the inbound aircraft was late, so this flight started late
airspace and airport capacity, including weather-driven flow control
Share of the delay minutes US DOT attributed to each cause for B6700 on LAX → FLL. Only delays of 15 minutes or more are attributed.

Does a late aircraft delay this flight?
How often the plane that flies B6700 comes in late, and what that does to the departure.
When the aircraft came in 15 or more minutes late, B6700 pushed back an average of 38 minutes late; when it came in on time or early, an average of 4 minutes late.
Each departure is matched to the flight the same aircraft flew into LAX just before it, using the tail number in the DOT file, 953 of 1,022 departures in all. A departure is left out when that flight is unknown, was cancelled or diverted, or the aircraft had sat for more than 12 hours. A flight the airline cancelled never left and is not in the count, and one flown by a substitute aircraft is matched to the aircraft that flew it, not to the one first planned.
Against the network at the same turn length
| Share of departures | Inbound landed 15+ late | Left 15+ late after a late inbound | Left 15+ late after an on-time inbound |
|---|---|---|---|
| B6700 | 25% | 60% | 12% |
| Network, same turn | 17% | 68% | 9% |
The schedule leaves a normal turn: enough time to clean and board if the aircraft is on time, little to spare if it is not.
The network row is every flight with a scheduled turn of 60 to 89 minutes. How often B6700’s aircraft landed 15 or more minutes late is higher than the network’s and, once the aircraft was late, how often B6700 left 15 or more minutes late is lower than the network’s.

From pushback to gate
When it leaves LAX late, does that still matter by the time it reaches FLL?
B6700 pushes back an average of 16.1 minutes late and reaches the gate at FLL an average of 6.8 minutes late. The 9.3 minutes between those two figures are slack the published schedule already carries, which is why a late pushback on this flight does not reliably become a late arrival. Its 16.7 minutes on the taxiways at LAX is about what any departure from the airport in that hour spends.
On arrival at FLL, B6700 spends 6.3 min taxiing from touchdown to the gate — ground time a connecting passenger sits through before they can even leave the aircraft, on top of however late the flight itself ran. That is 1.1 minutes shorter than a typical FLL arrival (7.4 min).
Departure delay is averaged over every pushback and arrival delay over every completed arrival, so the two counts differ by the flights that never reached FLL. Taxi-out is gate to wheels up and sits inside the scheduled block rather than on top of it; the comparison is 26,191 departures from LAX scheduled in the clock hour B6700 most often leaves in. Taxi-in is landing to gate, compared against every arrival FlyerIntel has on file at FLL (278,720 flights), not just B6700’s own. More on taxi time.

The hour it leaves LAX
Part of any flight’s record belongs to the clock rather than to the flight. B6700 has one departure time, so this is what that time is worth.
On-time arrival rate. 26,191 departures from LAX are scheduled in the 3 PM–4 PM hour over the period, against 595,153 across the whole day.
B6700 is scheduled out of LAX at 3:00 PM, in the 3 PM–4 PM bank. Departures from LAX in that hour arrive on time 78.2% of the time against 81.4% across the airport’s whole day — the slot alone is worth 3.2 points worse before anything about this particular flight is considered.
The two airport figures cover every departure from LAX to every destination, so they describe the slot rather than this journey — the like-for-like comparison against the route is above. Hours are scheduled local, and a number whose schedule moved between banks inside the period has no single hour and is not described here at all. Why the hour matters.

Does B6700 run worse on particular days?
Friday is historically the most reliable day and Monday the least, a gap of 6.7 percentage points.

Same airports, same journey, different odds of arriving on time.

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. B6700 is placed in the same ordering rather than left out of it; the rows around it are the most punctual departures on the route, not all of them, so this is a comparison and not a rank. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 1,025 records of B6700 operating LAX → FLL, published by the US DOT Bureau of Transportation Statistics. A flight counts as delayed when it arrives 15 or more minutes after schedule. Cancelled and diverted flights are excluded from the on-time rate and reported separately. Flight numbers are resolved as carrier plus number plus route, because the same number serves different routes over time.
