Holiday travel
Labor Day at SAT
San Antonio International Airport, San Antonio, TX. July 2023 – July 2026. Set against SAT’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 about the same in two and worse in one of the three years. The gap ran from 9.1 points below usual in 2025 to 2.9 points above usual in 2024.
0.97% of scheduled departures were cancelled across the Labor Day windows, against 0.69% on ordinary days of the same weekdays. It was lower in one of the three years.

Day by day
No single day has enough flights in one year to compare the years, so the days are ranked on all three years pooled: the Sunday before Labor Day ran lowest (83.7% on time, 1.0 point below usual) and Labor Day highest (85.2%, about level with usual). This cannot say whether the same day was worst or best in each year.

- Lowest to highest single year
- Lighter bars: days just outside the window
Bars show the on-time arrival rate and start at 60%, not zero.

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.

SAT beside every covered airport
Storms and outages move whole regions at once. This puts SAT’s year beside the year of all covered airports together, each against its own usual, to show whether SAT did better or worse than the network.
| Year | SAT on time | SAT, gap from usual | All airports on time | All airports, gap from usual |
|---|---|---|---|---|
| 2023Sep 2–4, 2023 | 88.2% | +2.6 | 87.4% | +7.6 |
| 2024Aug 31 – Sep 2, 2024 | 88.4% | +2.9 | 82.1% | +2.4 |
| 2025Aug 30 – Sep 1, 2025 | 76.4% | −9.1 | 82.2% | +2.5 |
