November next to SJC's other months
Against SJC's own year, November ran level with the twelve-month rate of 82.9%, which makes it number seven of twelve months, best first.

Either side of it, October ran 81.5% on time and December 81.2%, so this month sits in line with its neighbours.

Departure window
The best time of day to leave SJC in November
Departure time matters more here than the choice of carrier. The gap between the best and worst window is 16 points, against 8 points between the best and worst carrier. Each bar is the on-time rate for flights scheduled inside that window.
- 5am–8am745 flights91.3%
- 8am–11am733 flights87.2%
- 11am–2pm669 flights82.6%
- 2pm–5pm695 flights75.7%
- 5pm–8pm600 flights79.1%
- 8pm–5am217 flights75.1%
Scale runs 65% to 95%. Rows with fewer than 30 flights show a dash.
Book the early departure. Flights leaving between 5am–8am arrive on time 91.3% of the time, against 75.1% for the overnight window. That is 16 points of difference for no extra money, and it comes from the same aircraft having had no earlier flight to fall behind on. The 5am–8am window is the busiest, with 745 flights scheduled in it.
Across the week, Wednesday is the strongest day at 92.2% on time and Sunday the weakest at 75.7%. 17 points is a smaller lever than departure hour, but it is free.
Carrier by carrier
Which airlines ran best at SJC in November
The choice of carrier is not cosmetic here. SkyWest Airlines arrives on time 88.2% of the time; Southwest Airlines manages 79.9%. Sample sizes sit next to every figure, because a two-point gap across 2,199 flights means less than a ten-point one.
| Airline | Flights | On time | Avg delay | Cancelled | Grade |
|---|---|---|---|---|---|
| Southwest Airlines | 2,199 | 79.9% | 54 min | 0.86% | B+ |
| SkyWest Airlines | 671 | 88.2% | 64 min | 1.79% | A |

SkyWest leads Southwest by 8 points. Real, but small enough that a better departure time on the weaker carrier can outweigh it.

Delay causes
What held SJC 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 35,000 reported delay minutes.
- 40%Late-arriving aircraft
- 31%National Airspace System
- 25%Carrier
- 4%Extreme weather
- 1%Security
40% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. That is a cascade, and cascades start small and grow through the day. Across 35,000 reported delay minutes here, that single category outweighs weather by 11 to one. It is the strongest argument for booking the first departure of the morning, when the aircraft has been sitting at the gate overnight with nothing to inherit. The split is drawn from 35,334 reported delay minutes.
Cancellations sit at 1.12% against a national 2.49%, which is ordinary. Diversions add another 0.08%.
5.1% of arrivals land an hour or more late, close to the national 7.8%. 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.
