Holiday travel
Memorial Day at JAX
Jacksonville International Airport, Jacksonville, FL. July 2023 – July 2026. Set against JAX’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 Memorial Day (the last Monday of May). In the data: May 25–27, 2024; May 24–26, 2025; May 23–25, 2026. Three windows are in the data: enough to see whether a day repeats, not enough to call it a rule.
Compared with ordinary days, Memorial Day flights were about the same in one and worse in two of the three years. The gap ran from 9.5 points below usual in 2026 to 1.5 points below usual in 2025.
0.81% of scheduled departures were cancelled across the Memorial Day windows, against 1.32% 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 Memorial Day ran lowest (66.0% on time, 7.8 points below usual) and the Saturday before Memorial Day highest (75.8%, 2.6 points below usual). This cannot say whether the same day was worst or best in each year.

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.

JAX beside every covered airport
Storms and outages move whole regions at once. This puts JAX’s year beside the year of all covered airports together, each against its own usual, to show whether JAX did better or worse than the network.
| Year | JAX on time | JAX, gap from usual | All airports on time | All airports, gap from usual |
|---|---|---|---|---|
| 2024May 25–27, 2024 | 70.2% | −7.3 | 72.7% | −2.3 |
| 2025May 24–26, 2025 | 76.1% | −1.5 | 76.4% | +1.4 |
