Holiday travel
Labor Day at SMF
Sacramento International Airport, Sacramento, CA. July 2023 – July 2026. Set against SMF’s own ordinary days of the same weekday in the weeks around each holiday.
The window, year by year
The window runs the Saturday through the Monday, around Labor Day (the first Monday of September). In the data: Sep 2–4, 2023; Aug 31 – Sep 2, 2024; Aug 30 – Sep 1, 2025. Three windows are in the data: enough to see whether a day repeats, not enough to call it a rule.
Compared with ordinary days, Labor Day flights were better in two and about the same in one of the three years. The gap ran from 0.4 points above usual in 2024 to 3.6 points above usual in 2025.
0.39% of scheduled departures were cancelled across the Labor Day windows, against 0.94% on ordinary days of the same weekdays. It was lower in one of the three years.

Day by day
No day was the worst more than once: Monday, Sep 2 in 2024 and Saturday, Aug 30 in 2025.
The Sunday before Labor Day was the best day of the window in both years. Over the years it ran 89.2% on time, 7.2 points above an ordinary Sunday.

Bars show the on-time arrival rate and start at 60%, not zero. A dashed stub is a day with too few flights to print a rate.

A dash means fewer than 120 flights stood behind the figure, or behind the ordinary days it would be compared with: too few to print a rate, and nothing is estimated in its place. “Usual” is what ordinary days of the same weekday had at the same place in the weeks around the holiday, weighted by the flights being compared.

SMF beside every covered airport
Storms and outages move whole regions at once. This puts SMF’s year beside the year of all covered airports together, each against its own usual, to show whether SMF did better or worse than the network.

| 2023Sep 2–4, 2023 | 87.6% | +3.6 | 87.4% | +7.6 |
