Other routes B6306 has flown
A flight number is a slot in a schedule, and carriers reassign it. These are the other city pairs this number served in the analysis period.
| Route | Operated | Flights | On time |
|---|---|---|---|
| BNA→BOS Nashville to Boston | 2025-03-30 – 2026-03-30 | 96 | 92.6% |
| PBI→BDL West Palm Beach to Hartford | 2024-12-03 – 2024-12-18 | 16 | — |
Because the same number has served different journeys, the statistics above describe only the route B6306 currently operates. Blending them would produce an average of two different flights.
Why B6306 runs late
Where US DOT attributed the delay minutes on this flight.
crew, maintenance, boarding, fuelling — within the carrier’s control
airspace and airport capacity, including weather-driven flow control
the inbound aircraft was late, so this flight started late
screening or terminal security incidents
Share of the delay minutes US DOT attributed to each cause for B6306 on FLL → EWR. A single late flight can carry more than one cause, and only delays of fifteen minutes or more are attributed at all.
Other departures on FLL → EWR
Same airports, same journey — and not the same odds of arriving on time.
| Flight | Airline | On time | Median arrival | Operations |
|---|---|---|---|---|

Every departure listed carries at least 600 operations, so the comparison is between figures that mean something. Schedules change; confirm the departure still operates before booking around this.
Data and methodology
Calculated by FlyerIntel from 596 records of B6306 operating FLL → EWR, 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.
