Holiday travel
Labor Day at HNL
Daniel K. Inouye International Airport, Honolulu, HI. July 2023 – July 2026. Set against HNL’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 better in one and about the same in two of the three years. The gap ran from 2.1 points above usual in 2024 to 2.5 points above usual in 2023.
0.21% of scheduled departures were cancelled across the Labor Day windows, against 0.90% on ordinary days of the same weekdays. It was lower in two of the three years.

Bars show the on-time arrival rate and start at 70%, 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.

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

| 2023Sep 2–4, 2023 | 91.9% | +2.5 | 87.4% | +7.6 |
