15 of 67 late departures made up the time and arrived on time, 22% of them. In the other direction, 21 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 FLL.
The worst days
Worst days for B6 700
The latest arrival of the period was on 8 January 2026, 4 hours 22 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 |
|---|---|---|
| 8 January 2026 | 4 hours 22 minutes | Late-arriving aircraft |
| 4 February 2026 | 2 hours 56 minutes | Late-arriving aircraft |
| 6 September 2025 | 2 hours 33 minutes | Late-arriving aircraft |

Delay causes
Why B6 700 runs late
Late-arriving aircraft accounts for 49% of the 4,462 delay minutes carriers reported here, and the remaining four split what is left.
- 49%Late-arriving aircraft
- 35%Carrier
- 16%National Airspace System
49% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 4,462 reported delay minutes here, that single category outweighs weather by 49 to one. The split is drawn from 4,462 delay minutes reported on B6 700.
Cancellations are rare at 0.87%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
9.4% 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.
At 2,343 miles this is transcontinental flying, and long routes get a quiet structural advantage. Scheduled block time on a flight this length carries more padding in absolute minutes, so a twenty-minute late departure often still becomes an on-time arrival. Read the on-time rate here as slightly flattering next to a short-haul route with the same operational quality.
Every one of the 346 flights under B6 700 in the data flew LAX to FLL. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 346 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.
