B6 1286 lands a B, 6 points better than the national rate of 77.6%. About one flight in six arrives 15 minutes late or worse, and those flights are late by an hour and a half on average.

These figures cover 327 flights between July 2025 and June 2026. The median arrival is 11 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 1286 flies

B6 1286 flies PIT to BOS without a single fixed slot. Its most common scheduled departure was 10:00, used on 73 of 327 flights. 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 10:00 departure sits in the 8am–11am window. Across every US flight scheduled in that window the on-time rate is 84.1%, and B6 1286 runs level with that at 83.5%. 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 1286 quarter by quarter

B6 1286 did not run the same all year. Its best quarter was Jul–Sep 2025 at 90.1% on time and its weakest Jan–Mar 2026 at 74.2%, a swing of 16 points on roughly 82 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.

Delay causes

Why B6 1286 runs late

One category carries most of the weight here. Late-arriving aircraft accounts for 50% of the 4,535 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
    50%
  • Extreme weather
    21%
  • National Airspace System
    18%
  • Carrier
    11%

Extreme weather accounts for 21% of delay minutes, well above the single-digit share typical across the system. Weather delays are lumpy: they arrive as whole bad days rather than as a steady drag, so the quarterly figures above are the more useful view of the risk. The national share is 6%, so this operation carries roughly 3.3 times the usual weather exposure. The split is drawn from 4,535 delay minutes reported on B6 1286.

Cancellations sit at 1.83% against a national 1.81%, which is ordinary. Diversions add another 0.00%.

Connections and routes

What a delay on this flight costs

5.3% 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 327 flights under B6 1286 in the data flew PIT 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. 327 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
