Holiday travel at SEA
Seattle-Tacoma International Airport, Seattle, WA. July 2023 – July 2026. Set against SEA’s own ordinary days of the same weekday in the weeks around each holiday.
The five holidays at SEA
At SEA every holiday with a figure ran at or above ordinary days; Labor Day did best (+8.0 points) and Christmas to New Year’s came closest to usual (+0.9).
Each row pools every year of that holiday’s window at SEA and sets it against SEA’s own ordinary days of the same weekdays in the weeks around it. Open a holiday for its day-by-day figures.

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.
