How to Find Cheap Flights to Europe

To get the best price, use Google Flights to track fares for your exact dates and book 3 to 6 months in advance. Avoid flying on weekends and prioritize booking multi-city or open-jaw tickets if you are visiting more than one country.

Use Google Flights Explore. Instead of entering a specific city, enter your origin and set the destination to 'Europe'. Use the map view to see which cities have the lowest fares for your preferred dates.
Set up fare alerts. Once you have a target destination and a rough timeframe, toggle the 'Track prices' switch on Google Flights. You will receive an email whenever the price drops significantly.
Look for secondary airports. Major hubs like London (LHR), Paris (CDG), or Frankfurt (FRA) are expensive. Check flights into secondary hubs like Dublin (DUB), Milan (MXP), or Brussels (BRU) and then take a budget airline (Ryanair/EasyJet) for the final leg.
Book at the 3-6 month window. For international flights to Europe, booking 12 to 24 weeks out is the sweet spot. Don't wait until the last 3 weeks unless you have flexible destination choices.
