Best Times to Book Flights for Deals

Airlines offer the lowest fares for domestic flights booked one to two months ahead and international trips three to five months in advance. Midweek flights, especially Wednesdays, provide the cheapest options over weekends. For 2026 spring break in late March or early April, book now in late January or early February to catch fare drops. Fridays emerge as a strong booking day, with flexibility trumping the exact day.
