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 287 flies

B6 287 flies BOS to LAX without a single fixed slot. Its most common scheduled departure was 06:00, used on 122 of 327 flights, with 06:25 (56 flights) and 07:00 (44 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 287 runs 4 points worse at 85.4%. 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 287 quarter by quarter

B6 287 did not run the same all year. Its best quarter was Jul–Sep 2025 at 96.4% on time and its weakest Jan–Mar 2026 at 70.8%, a swing of 26 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.

By weekday, B6 287 did best on Friday at 91.3% on time and worst on Tuesday at 78.6%. Each day rests on about 47 flights, so a gap of 13 points is worth noticing but could still narrow in another year.

Delay causes

Why B6 287 runs late

One category carries most of the weight here. Carrier accounts for 44% of the 3,019 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
44%
National Airspace System
37%
Late-arriving aircraft
18%
Extreme weather
1%

37% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,106 minutes out of 3,019, against a national NAS share of 21%. The split is drawn from 3,019 delay minutes reported on B6 287.

Cancellations sit at 1.53% against a national 1.81%, which is ordinary. Diversions add another 0.31%.

Connections and routes

What a delay on this flight costs

Badly late arrivals are rare here: only 4.4% 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.

At 2,611 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 327 flights under B6 287 in the data flew BOS to LAX. 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.
