These figures cover 365 flights between July 2025 and June 2026. The median arrival is 14 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 676 flies

B6 676 flies BDL to JFK without a single fixed slot. Its most common scheduled departure was 06:00, used on 140 of 365 flights, with 07:12 (64 flights) and 07:10 (61 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 06:00 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 676 runs level with that at 91.0%. 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 676 quarter by quarter

B6 676 did not run the same all year. Its best quarter was Apr–Jun 2026 at 95.6% on time and its weakest Oct–Dec 2025 at 85.4%, a swing of 10 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 676 ranged from 88.0% on Sunday to 96.2% on Tuesday. With about 52 flights behind each day, a spread of 8 points is inside normal variation, so the day you fly is not worth changing for this flight.

Delay causes

Why B6 676 runs late

One category carries most of the weight here. Carrier accounts for 80% of the 2,573 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.

Carrier
80%

The largest share of delay minutes, 80%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. Unlike weather, that is a management outcome, and it is the category where the gap between two carriers on the same schedule is genuinely earned. It accounts for 2,053 of the 2,573 delay minutes reported here. The split is drawn from 2,573 delay minutes reported on B6 676.

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

Badly late arrivals are rare here: only 2.2% land an hour or more behind schedule, against 8.1% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.

Every one of the 365 flights under B6 676 in the data flew BDL to JFK. 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 676
