For domestic economy routes from William P. Hobby Airport (HOU), the optimal booking window is generally 21–60 days before departure; international economy fares often require 2–4 months of lead time. Cheapest travel months commonly include January, September, and mid-October. For last-minute savings on certain routes, search 7–14 days before departure for flash sales, but this is riskier for popular holiday periods.
