These figures cover 365 flights between July 2025 and June 2026. Beyond the headline rate, 12.9% 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 675 flies

B6 675 flies JFK to BDL without a single fixed slot. Its most common scheduled departure was 22:45, used on 82 of 365 flights, with 21:25 (53 flights) and 22:30 (52 flights) next. Carriers retime flights through the season, so the rates here blend slightly different positions in the aircraft's day.

A 22:45 departure sits in the 8pm–5am window. Across every US flight scheduled in that window the on-time rate is 70.5%, and B6 675 runs 7 points worse at 63.5%. By that time of day most aircraft have flown several legs already, and whatever went wrong earlier is still in the schedule.

Across the year

B6 675 quarter by quarter

B6 675 did not run the same all year. Its best quarter was Apr–Jun 2026 at 75.6% on time and its weakest Jan–Mar 2026 at 56.3%, a swing of 19 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.

By weekday, B6 675 did best on Tuesday at 76.9% on time and worst on Saturday at 51.0%. Each day rests on about 52 flights, so a gap of 26 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 675 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 47% of the 8,056 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.

47% 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 8,056 reported delay minutes here, that single category outweighs weather by 5 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 8,056 delay minutes reported on B6 675.

Cancellations sit at 2.47% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

For anyone connecting, the number to weigh is not the on-time rate but the tail behind it. 12.9% of arrivals land a full hour or more behind schedule, against 8.1% nationally. A 45-minute layover does not survive that, and no amount of walking quickly changes it. Ninety minutes is the honest minimum here, and two hours if the onward flight is on a separate ticket.

Every one of the 365 flights under B6 675 in the data flew JFK to BDL. 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 675

For a booking, B6 675 is a flight to put a long connection behind. 12.9% of its completed flights arrived an hour or more late, which a short layover will not absorb. If the onward flight is on a separate ticket, the risk sits with you.
