How we got these numbers

Domestic and international booking windows come from Google's 2021-2025 flight pricing study and Expedia's 2026 Air Hacks for Six report. Holiday windows come from Expedia's holiday travel breakdown and Going.com's 2026 fare trend data. Penalty ranges (10% early premium, 35% late-booking premium, 13% in-window savings) reflect average deviations in the same public datasets.
