For domestic economy flights, the best time to book is often 3–8 weeks before departure; international economy fares are usually cheapest 2–5 months ahead. Travel on Tuesdays, Wednesdays, and Saturdays to find lower demand and reduced fares. Shoulder seasons (September–November and January–March) typically deliver the most savings, while summer and holiday peaks require earlier booking and flexibility to achieve reasonable economy pricing.
