These figures cover 365 flights between September 2025 and August 2026. The median arrival is 2 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Across the year
B6 1700 quarter by quarter

Share of 358 completed flights by arrival against schedule.
Time lost at the gate mostly stays lost. Of 64 departures that left 15 minutes late or more, only 6 made it up before arrival. In the other direction, 35 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.

Delay causes
Why B6 1700 runs late
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 5,144 reported delay minutes.
- 40%Late-arriving aircraft
- 30%National Airspace System
- 30%Carrier
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 5,144 reported delay minutes here, that single category outweighs weather by 40 to one. The split is drawn from 5,144 delay minutes reported on B6 1700.
Cancellations sit at 1.37% against a national 1.89%, which is ordinary. Diversions add another 0.55%.
Connections and routes
What a delay on this flight costs
7.3% 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 about an hour, which a normal layover absorbs.
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 365 flights under B6 1700 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. 365 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.
