These figures cover 358 flights between July 2025 and June 2026. The median arrival is 9 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 374 flies

B6 374 flies SYR to BOS without a single fixed slot. Its most common scheduled departure was 06:00, used on 201 of 358 flights, with 07:00 (60 flights) and 07:45 (59 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 374 runs 9 points worse at 80.6%. 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 374 quarter by quarter

B6 374 did not run the same all year. Its best quarter was Jul–Sep 2025 at 93.0% on time and its weakest Jan–Mar 2026 at 66.7%, a swing of 26 points on roughly 90 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.

Jan–Mar 202690 flights66.7%

Scale runs 60% to 100%. Rows with fewer than 30 flights show a dash.

By weekday, B6 374 did best on Saturday at 92.3% on time and worst on Sunday at 72.3%. Each day rests on about 51 flights, so a gap of 20 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 374 runs late

One category carries most of the weight here. Carrier accounts for 64% of the 5,665 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.

The largest share of delay minutes, 64%, 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 3,628 of the 5,665 delay minutes reported here. The split is drawn from 5,665 delay minutes reported on B6 374.

Cancellations sit at 2.23% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

6.3% 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 an hour and a half, which a normal layover absorbs.

Every one of the 358 flights under B6 374 in the data flew SYR to BOS. 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. 358 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.

Booking B6 374
