Booking flights at the right time is one of the most effective ways to reduce travel costs. Industry data consistently shows that most domestic flights are cheapest when booked 1–3 months in advance, while international routes favour a 3–6 month window.
The 6-Week Sweet Spot
For short-haul European flights, research by flight analytics firms points to a "sweet spot" of roughly 6 weeks before departure. Prices tend to be highest within 2 weeks of travel and in the first few days after tickets go on sale.
Day of the Week Matters
Tuesdays and Wednesdays are historically the cheapest days to fly, while Fridays and Sundays command a premium. Booking on a Tuesday afternoon can also yield slightly lower fares as airlines adjust pricing after Monday deals close.
Use Price Alerts
Set up fare alerts on tools like Google Flights or Skyscanner. Once a route you want drops to your target price, book immediately — fares can rebound within hours.
Off-Peak Travel Windows
January, February, and early November are typically the cheapest months to fly globally. School holiday periods (Christmas, Easter, summer) always see inflated prices regardless of how far in advance you book.
