How to Find the Cheapest Flights to Europe in 2025

Europe’s charm—from the canals of Amsterdam to the beaches of the Greek Isles—calls out to travelers. Luckily, with smart strategies, cheap flights to Europe are more attainable than ever, even during peak seasons. This guide reveals insider tips for securing the lowest airfare, including how to use powerful tools like Expedia, Booking.com and Aviasales.

1. Book at the Ideal Time

  • International Tickets: Lock in flights 2–6 months before departure for the best rates. According to Booking.com experts, this window is ideal for long-haul fares .

  • Domestic U.S. Flights: Generally more flexible, but aim for 3–6 weeks ahead .

  • Midweek Savings: Start searches and schedule flights midweek—Tuesday through Thursday tends to be the most affordable .

  • Off-Peak Perks: Avoid high seasons like July–August or major holidays. Autumn and early spring often bring 20–30% savings

2. Be Flexible with Your Dates & Airports

  • Use Booking.com’s flexible date grid to compare month-over-month prices.

  • Leverage Aviasales’ “Price Map” feature to find the cheapest destinations regionally.

  • Consider secondary airports—London Stansted, Paris Beauvais, or Rome Ciampino often offer steeper savings .

3. Use Multiple Search Tools

  • Aviasales helps you compare fares across all airlines and agencies; it only redirects you to the provider’s site to finalize the booking

  • Booking.com Flights offers transparent pricing without hidden fees, especially when bundling with hotels .

  • Don’t forget Google Flights, Skyscanner, and Momondo for comprehensive searches.

4. Set Fare Alerts & Track Prices

Price-tracking tools notify you of drops or flash sales:

  • Booking.com: Set date and route alerts to stay on top of price changes

  • Aviasales: Use push notifications and subscriptions to monitor prices .

  • Error Fares: Websites like Secret Flying monitor for unexpected fare glitches—be ready to jump on deals

5. Consider Budget Airlines & Alternatives

  • In Europe: Carriers like Ryanair, easyJet, Wizz Air, and Vueling offer €15–€50 flights—just avoid weekend booking and extra fees

  • Long-haul budget: French Bee offers transatlantic flights around $300 one-way .

  • Always compare with full-service carriers to ensure total cost remains lower.

6. Multi-City & Open-Jaw Hacks

Booking multi-city or open-jaw tickets often saves money and adds flexibility. For example, flying into Madrid and returning from Barcelona might be cheaper than a round-trip ticket

7. Use Currency & Cashback Hacks

  • Currency advantage: Compare fares in GBP, EUR, or local currency; sometimes it’s cheaper—even after conversion fees .

  • Cashback & discounts: Use affiliate sites or credit cards with travel rewards for extra savings .

8. Smart Booking Day Strategies

Booking midweek flights is generally more affordable. While Tuesday bookings aren’t always the cheapest, midweek remains optimal .

9. Final Booking Tactics: Direct vs Aggregated

  • Booking directly may simplify issues like cancellations.

  • Aggregators like Aviasales and Booking.com help compare offers, but complete booking via the airline’s site to ensure easier support.
