When is the Best time to Book International Flight Tickets? The best time to book international flight tickets often depends on your destination, travel season, and flexibility. Generally, it’s recommended to book 2–6 months in advance for the best deals, as airlines offer competitive prices during this window. For peak travel times like holidays or summer vacations, booking even earlier—around 6–12 months ahead—can save money and secure your preferred schedule. Mid-week purchases, particularly on Tuesdays or Wednesdays, often yield better fares. Consider flying midweek or during off-peak hours for additional savings. Flexibility with travel dates and using fare comparison tools can also help you secure the most affordable options.
