These figures cover 11,385 departures from Boston Logan International in November 2025. On time means an arrival less than 15 minutes after the scheduled gate time, the DOT's threshold, and the national comparison uses every US departure in the same month rather than the whole year.
Against the year
November next to BOS's other months
Against BOS's own year, November ran 3 points better than the twelve-month rate of 74.6%, which makes it number three of twelve months, best first. Either side of it, October ran 73.9% on time and December 68.7%, so a trip moved by a few weeks would have landed in a worse stretch.

Carrier by carrier
Which airlines ran best at BOS in November
The choice of carrier is not cosmetic here. United Airlines arrives on time 80.6% of the time; JetBlue Airways manages 74.4%. Sample sizes sit next to every figure, because a two-point gap across 2,981 flights means less than a ten-point one.

| JetBlue Airways | 2,981 | 74.4% | 70 min | 2.92% | C |

Republic Airways cancels 4.5% of what it schedules here, the highest in the table. A cancelled flight never appears in an on-time rate, so read that column alongside the punctuality one rather than after it.

Delay causes
What held BOS up in November
Carriers report a reason for every delay minute they cause, in five DOT categories. The split below is by minutes, not by number of flights, so a handful of very long weather delays weighs as much as many short ones. It covers 182,000 reported delay minutes.
- 40%Late-arriving aircraft
- 30%Carrier
- 30%National Airspace System
- 0%Extreme weather
- 0%Security
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 182,000 reported delay minutes here, that single category outweighs weather by 40 to one. The split is drawn from 181,822 reported delay minutes.
Cancellations run at 2.76%, against 2.49% nationally. That is roughly one flight in 40 cancelled outright. A cancelled flight is invisible in every on-time figure on this page, so the punctuality numbers above describe only the flights that actually operated.
9.3% of arrivals land a full hour or more behind schedule, against 7.8% nationally. Ninety minutes is the honest minimum for a connection here, and two hours if the onward flight is on a separate ticket.
What to do with this
Flying from BOS in November
For a November trip through BOS: this is one of the better months to be flying from here, 78.0% on time with 2.76% cancelled. That is a base rate for the month as a whole; a single storm can still spoil a particular day.
