B6 816 lands a B, 4 points better than the national rate of 77.6%. Roughly one flight in five arrives 15 minutes late or worse, and those flights are late by a little over an hour on average. That is a workable record, not a spotless one. That rests on 357 flights, with a median arrival 12 minutes early.

Set against the rest of the country, B6 816's record is 4 points better than the US average of 77.6%. That gap is worth roughly 41 fewer late arrivals for every thousand flights.

These figures cover 357 flights between July 2025 and June 2026. Beyond the headline rate, 8.0% 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 816 flies

B6 816 flies SFO to JFK without a single fixed slot. Its most common scheduled departure was 07:00, used on 130 of 357 flights, with 22:30 (66 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 816 runs 8 points worse at 81.7%. 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 816 quarter by quarter

B6 816 did not run the same all year. Its best quarter was Jan–Mar 2026 at 85.2% on time and its weakest Apr–Jun 2026 at 72.6%, a swing of 13 points on roughly 89 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 816 did best on Tuesday at 90.4% on time and worst on Monday at 74.0%. Each day rests on about 51 flights, so a gap of 16 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 816 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 61% of the 4,588 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.

Late-arriving aircraft
61%
Carrier
22%
National Airspace System
16%

61% 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 4,588 reported delay minutes here, that single category outweighs weather by 61 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 4,588 delay minutes reported on B6 816.

Cancellations sit at 1.68% against a national 1.81%, which is ordinary. Diversions add another 0.56%.

Connections and routes

What a delay on this flight costs

8.0% 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.

At 2,586 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 357 flights under B6 816 in the data flew SFO 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. 357 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 816
