How this page is built

These figures come from AwardTool's cached award searches across 29 loyalty programs. A value counts only when AwardTool observed it in the last 30 days, for departures within 365 days of the data date. Each price is the lowest one-way award seen per passenger, in the program's points or miles, with taxes and fees in USD. A missing value means AwardTool hasn't seen that award recently, not that none exists. The date-by-date calendar is in the app: a limited window on the free plan and 365 days with Pro.
