These figures cover 311 flights between July 2025 and June 2026. The median arrival is 6 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 1708 flies

B6 1708 flies LAS to FLL without a single fixed slot. Its most common scheduled departure was 12:10, used on 46 of 311 flights, with 11:29 (34 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

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

A 12:10 departure sits in the 11am–2pm window. Across every US flight scheduled in that window the on-time rate is 78.8%, and B6 1708 runs 4 points worse at 75.0%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Delay causes

Why B6 1708 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 44% of the 4,030 delay minutes carriers reported, and the remaining four split what is left. The split is by minutes rather than by flights, so a few very long delays count for as much as many short ones.

Extreme weather
1%

44% 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 4,030 reported delay minutes here, that single category outweighs weather by 44 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 4,030 delay minutes reported on B6 1708.

Cancellations sit at 1.61% against a national 1.81%, which is ordinary. Diversions add another 0.64%.

Connections and routes

What a delay on this flight costs

5.9% 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 roughly 55 minutes, which a normal layover absorbs.

At 2,173 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 311 flights under B6 1708 in the data flew LAS 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. 311 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.

Booking B6 1708
