Best Booking Windows: When to Buy Flights for the Lowest Prices in 2025

Want to score the best airfare in 2025? It’s not just about where you fly—it’s about when you book. Airlines use dynamic pricing algorithms, but after years of data analysis, travel pros have narrowed down the best booking windows to save you serious money.

📅 What Is a “Booking Window”?

It's the ideal number of days before departure when airfare tends to be lowest. Booking too early or too late often results in paying more than necessary. Let’s break it down by region.

🌍 Domestic Flights (Australia, USA, UK)

• Best time to book: 1 to 3 months in advance
• Worst time: Last 7 days before departure
• Pro tip: Use price alerts from Skyscanner to monitor fares

✈️ International Flights

• Best time to book: 2.5 to 6 months in advance
• Exception: For peak seasons (e.g., December holidays), book 6–9 months early
• Pro tip: Tuesdays and Wednesdays often show cheaper fares

💼 Business Class & Premium Seats

• Best time to book: 1 to 4 months ahead (business class promos drop closer to departure)
• Pro tip: Look out for airline flash sales or use WayAway Plus
