When Is The Best Time To Book International Flight Tickets? When it comes to booking international flights, timing can make all the difference. A sweet spot is often 3-6 months before your travel date. During this window, airlines usually release competitive fares, and you can snag great deals before prices start climbing. If you're traveling during peak seasons like summer or holidays, aim for the earlier end of that range to avoid last-minute surges. Midweek departures and flights booked on Tuesdays or Wednesdays tend to be cheaper too. Plan ahead, stay flexible, and your wallet will thank you.
