These figures cover 335 flights between September 2025 and August 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.

Share of 328 completed flights by arrival against schedule.
10 of 40 late departures made up the time and arrived on time, 25% of them. In the other direction, 19 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at LAX.
The worst days
Worst days for B6 287
The latest arrival of the period was on 6 March 2026, 6 hours 54 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). The same cause led on three of the five worst days.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 6 March 2026 | 6 hours 54 minutes | Carrier |
| 18 November 2025 | 3 hours 42 minutes | Carrier |
| 3 December 2025 | 3 hours 14 minutes | Carrier |
| 18 April 2026 | 2 hours 18 minutes | Late-arriving aircraft |
| 27 December 2025 | 2 hours 10 minutes | National Airspace System |
Delay causes
Why B6 287 runs late
Carrier accounts for 42% of the 2,791 delay minutes carriers reported here, and the remaining four split what is left.
- 42%Carrier
- 40%National Airspace System
- 15%Late-arriving aircraft
- 2%Extreme weather
40% 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 1,124 minutes out of 2,791, against a national NAS share of 21%. The split is drawn from 2,791 delay minutes reported on B6 287.
Cancellations sit at 1.79% against a national 1.89%, which is ordinary. Diversions add another 0.30%.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 4.0% land an hour or more behind schedule, against 8.3% 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 335 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. 335 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.
