You've probably heard conflicting advice about when to book flights — some say 6 weeks ahead, others say 3 months. The truth is more nuanced. For European short-haul flights, the data consistently shows that the cheapest fares appear in two windows: the very early booking period (3–6 months ahead for summer, 6–8 weeks for shoulder season) and a brief late-booking window (4–10 days before departure) when airlines dump remaining seats. Avoid the expensive middle ground of 2–4 weeks out, when business travelers book and airlines know demand is high.
Compare top providers and find the best deal for your trip.
The 'book on Tuesday' myth has largely been debunked for modern dynamic pricing, but some patterns hold. Flying midweek (Tuesday through Thursday) is typically cheaper than weekend flights because business traveler demand is concentrated on Mondays and Fridays. Similarly, early morning and late evening flights are cheaper than mid-day departures. For booking itself, search engines refresh airline price data overnight, so checking early morning on a weekday can surface freshly loaded cheap fares. Using Incognito/Private mode prevents search tools from tracking your interest and potentially raising prices.

Google Flights' price calendar view is one of the most powerful tools available — it shows the cheapest fare for every date in a month at a glance. Skyscanner's 'Cheapest month' filter reveals the lowest prices across a three-month window. Hopper (app) uses machine learning to predict whether prices will rise or fall and alerts you to the optimal booking moment. Setting price drop alerts on Google Flights for your specific route is particularly effective — you'll be notified whenever the price changes, so you can book at the lowest point without constantly checking manually.

For summer travel (June–August) to popular European destinations, book 3–4 months in advance for the best combination of availability and price. Booking earlier than 6 months rarely saves money, as airlines haven't yet priced competitively.
The Tuesday booking myth is largely outdated. Airlines now use dynamic pricing algorithms that update continuously. However, midweek searches (Tuesday–Thursday) can find slightly cheaper fares due to lower demand for travel departures on those days.
There is limited evidence that search history causes prices to rise, as most fare data is pulled in real-time. However, using Incognito mode is still recommended as a precaution — it prevents cookies from influencing displayed prices and ensures you're seeing fresh results.
