These figures cover 365 flights between July 2025 and June 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.

Schedule

When B6 1700 flies

B6 1700 flies LAX to FLL without a single fixed slot. Its most common scheduled departure was 08:00, used on 64 of 365 flights, with 08:20 (53 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

Scale runs 0% to 100%. Rows with fewer than 30 flights show a dash.

Share of scheduled departures at each local time. Times used on fewer than one flight in ten are not listed.

A 08:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 1700 runs 10 points worse at 74.5%. Early departures usually start with an aircraft that has not flown yet that day, which is most of why the window does well.

Across the year

B6 1700 quarter by quarter

B6 1700 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.2% on time and its weakest Jan–Mar 2026 at 60.5%, a swing of 33 points on roughly 91 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Jul–Sep 202592 flights93.2%
Oct–Dec 202592 flights68.5%
Jan–Mar 202690 flights60.5%
Apr–Jun 202691 flights75.8%

Scale runs 50% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, B6 1700 did best on Tuesday at 80.8% on time and worst on Thursday at 63.5%. Each day rests on about 52 flights, so a gap of 17 points is worth noticing but could still narrow in another year.

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 5,032 reported delay minutes.

Late-arriving aircraft
40%
National Airspace System
30%
Carrier
29%

40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 5,032 reported delay minutes here, that single category outweighs weather by 40 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 5,032 delay minutes reported on B6 1700.

Cancellations sit at 1.10% against a national 1.81%, which is ordinary. Diversions add another 1.10%.

Connections and routes

What a delay on this flight costs

7.0% of arrivals land an hour or more late, close to the national 8.1%. That is the figure that decides a connection, and it says 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.

What to do with this

Booking B6 1700
