Holiday travel
July 4 at MCI
Kansas City International Airport, Kansas City, MO. July 2023 – July 2026. Set against MCI’s own ordinary days of the same weekday in the weeks around each holiday.
The window, year by year
The window runs July 1 through July 5, around July 4, whatever weekday it falls on. In the data: Jul 1–5, 2023; Jul 1–5, 2024; Jul 1–5, 2025; Jul 1–5, 2026. July 4 fell on a Tuesday in 2023, Thursday in 2024, Friday in 2025, and Saturday in 2026. Four windows are in the data: enough to see whether a day repeats, not enough to call it a rule.
Compared with ordinary days, July 4 flights were better in two and about the same in two of the four years. The gap ran from 0.4 points above usual in 2023 to 11.8 points above usual in 2024.
1.30% of scheduled departures were cancelled across the July 4 windows, against 1.76% on ordinary days of the same weekdays. It was lower in one of the four 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.

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