Holiday travel
Thanksgiving at PDX
Portland International Airport, Portland, OR. July 2023 – July 2026. Set against PDX’s own ordinary days of the same weekday in the weeks around each holiday.
The window, year by year
The window runs the Wednesday before through the Sunday after, around Thanksgiving Day (the fourth Thursday of November). In the data: Nov 22–26, 2023; Nov 27 – Dec 1, 2024; Nov 26–30, 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, Thanksgiving flights were about the same in two and worse in one of the three years. The gap ran from 3.6 points below usual in 2025 to 0.6 points above usual in 2024.
0.33% of scheduled departures were cancelled across the Thanksgiving windows, against 0.59% 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.

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