Holiday travel
Christmas to New Year’s at AUS
Austin-Bergstrom International Airport, Austin, TX. July 2023 – July 2026. Set against AUS’s own ordinary days of the same weekday in the weeks around each holiday.
The window, year by year
The window runs December 23 through January 2, around Christmas Day (December 25). In the data: Dec 23, 2023 – Jan 2, 2024; Dec 23, 2024 – Jan 2, 2025; Dec 23, 2025 – Jan 2, 2026. Christmas Day fell on a Monday in 2023, Wednesday in 2024, and Thursday in 2025. Three windows are in the data: enough to see whether a day repeats, not enough to call it a rule.
Christmas to New Year’s flights ran worse than ordinary days in all three years. The gap ran from 6.0 points below usual in 2024 to 4.5 points below usual in 2023.
0.77% of scheduled departures were cancelled across the Christmas to New Year’s windows, against 1.37% 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.

AUS beside every covered airport
Storms and outages move whole regions at once. This puts AUS’s year beside the year of all covered airports together, each against its own usual, to show whether AUS did better or worse than the network.
| Year | AUS on time | AUS, gap from usual | All airports on time | All airports, gap from usual |
|---|---|---|---|---|
| 2023Dec 23, 2023 – Jan 2, 2024 | 77.2% | −4.5 | 81.0% | +2.2 |
| 2024Dec 23, 2024 – Jan 2, 2025 | 76.1% | −6.0 | 76.2% | −3.4 |
