These figures cover 345 flights between July 2025 and June 2026. The median arrival is 3 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 1476 flies
B6 1476 flies SJU to BDL without a single fixed slot. Its most common scheduled departure was 06:01, used on 84 of 345 flights, with 07:00 (70 flights) and 05:01 (45 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 06:01 departure sits in the 5am–8am window. Across every US flight scheduled in that window the on-time rate is 89.3%, and B6 1476 runs 15 points worse at 74.7%. 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 1476 quarter by 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.

Delay causes
Why B6 1476 runs late
One category carries most of the weight here. Carrier accounts for 47% of the 5,263 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%Carrier
- 30%National Airspace System
- 21%Late-arriving aircraft
- 2%Extreme weather
The largest share of delay minutes, 47%, 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 2,485 of the 5,263 delay minutes reported here. The split is drawn from 5,263 delay minutes reported on B6 1476.
Cancellations sit at 2.03% against a national 1.81%, which is ordinary. Diversions add another 0.58%.
Connections and routes
What a delay on this flight costs
6.5% 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 about an hour, which a normal layover absorbs.
At 1,666 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 345 flights under B6 1476 in the data flew SJU 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. 345 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.
