These figures cover 288 flights between July 2025 and June 2026. Beyond the headline rate, 8.5% of arrivals land a full hour or more behind schedule. That is the number that wrecks a connection, and it is not visible in an on-time percentage alone.

Schedule

When B6 716 flies

B6 716 flies BUF to BOS without a single fixed slot. Its most common scheduled departure was 07:00, used on 74 of 288 flights, with 07:22 (58 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 07:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 716 runs 9 points worse at 80.4%. 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 716 quarter by quarter

B6 716 did not run the same all year. Its best quarter was Apr–Jun 2026 at 91.1% on time and its weakest Jan–Mar 2026 at 62.3%, a swing of 29 points on roughly 72 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 716 did best on Wednesday at 86.1% on time and worst on Friday at 70.5%. Each day rests on about 41 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 716 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 48% of the 3,778 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.

48% 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 3,778 reported delay minutes here, that single category outweighs weather by 48 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 3,778 delay minutes reported on B6 716.

Cancellations sit at 2.43% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

8.5% 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 a little over an hour, which a normal layover absorbs.

The same number turns up on one other city pair in the data, including SFO to JFK (14), but none flew often enough under B6 716 to report a rate for. Carriers move flight numbers between routes, so the figures on this page apply to BUF to BOS only.

One caution: this is a thin sample. 288 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 716

For a booking, read B6 716 as 80.4% on time with 2.43% cancelled over 288 flights. Those are rates from the past twelve months, not a forecast for any particular day.
