These figures cover 271 flights between July 2025 and June 2026. The median arrival is 3 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 2941 flies

B6 2941 flies STX to SJU without a single fixed slot. Its most common scheduled departure was 14:23, used on 55 of 271 flights, with 14:39 (37 flights) and 15:51 (37 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 14:23 departure sits in the 2pm–5pm window. Across every US flight scheduled in that window the on-time rate is 72.4%, and B6 2941 runs 4 points better at 76.4%. Midday slots inherit some of the morning's delays without yet carrying the full weight of the evening's.

Across the year

B6 2941 quarter by quarter

B6 2941 did not run the same all year. Its best quarter was Jul–Sep 2025 at 82.3% on time and its weakest Oct–Dec 2025 at 70.1%, a swing of 12 points on roughly 68 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.

By weekday, B6 2941 did best on Wednesday at 84.6% on time and worst on Saturday at 62.9%. Each day rests on about 39 flights, so a gap of 22 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 2941 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 67% of the 3,349 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.

67% 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 3,349 reported delay minutes here, that single category outweighs weather by 67 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 3,349 delay minutes reported on B6 2941.

Cancellations sit at 1.11% against a national 1.81%, which is ordinary. Diversions add another 0.37%.

Connections and routes

What a delay on this flight costs

5.2% 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.

Every one of the 271 flights under B6 2941 in the data flew STX to SJU. 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. 271 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 2941

For a booking, read B6 2941 as 76.4% on time with 1.11% cancelled over 271 flights. Those are rates from the past twelve months, not a forecast for any particular day.
