Holiday travel
Memorial Day at MSY
Louis Armstrong New Orleans International Airport, New Orleans, LA. July 2023 – July 2026. Set against MSY’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 better in one and about the same in two of the three years. The gap ran from 3.5 points below usual in 2026 to 4.6 points above usual in 2024.
0.67% of scheduled departures were cancelled across the Memorial Day windows, against 1.10% on ordinary days of the same weekdays. It was lower in one of the three years.

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.

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