Holiday travel

Labor Day at MIA

Miami International Airport, Miami, FL. July 2023 – July 2026. Set against MIA’s own ordinary days of the same weekday in the weeks around each holiday.

History, not a forecast. This shows what happened in past holiday windows. It cannot say what this year will bring, and each holiday appears only a few times in the data, so one bad storm can decide a whole year. Check your airline for your own flight.

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 one and worse in two of the three years. The gap ran from 10.6 points below usual in 2024 to 17.6 points above usual in 2023.

0.69% of scheduled departures were cancelled across the Labor Day windows, against 1.15% on ordinary days of the same weekdays. It was lower in two 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.

MIA beside every covered airport

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