How to Find the Cheapest Flights in Europe: 2025 Edition
Traveling across Europe doesn’t have to cost a fortune — in fact, if you know where to look and how to book, you can fly between cities for the price of a dinner. With more low-cost airlines, better price tracking tools, and strategic booking habits, 2025 is shaping up to be a fantastic year for budget travelers.
Whether you’re planning a weekend getaway, a multi-city adventure, or a spontaneous trip, this guide will show you how to find the cheapest flights in Europe in 2025 — and how to book them without stress.
1. Use a Flight Aggregator to Compare All Options
The first and most important step is to use a flight aggregator — a tool that scans hundreds of airlines, including low-cost carriers, to find the best prices.
Best Options for Europe:
- Skyscanner — Great for flexible date searches
- Travelupo — Built specifically for comparing deals across Europe
- Google Flights — Visual calendar to quickly spot low fares
Pro Tip: Use the “Everywhere” search function on Skyscanner or Travelupo to discover unexpected cheap routes.
2. Book at the Right Time
Timing is everything when it comes to cheap flights.
When to Book:
- 4–8 weeks in advance for domestic European flights
- Tuesday and Wednesday are usually the cheapest days to fly
- Avoid Fridays and Sundays, especially for short weekend trips
Bonus Tool:
Use the price alert feature on flight aggregators to get notified when a fare drops.

3. Be Flexible with Your Dates
If you have flexibility in your travel dates, you can save a significant amount. A one-day difference can cut your price by 50%.
Look for:
- Midweek departures (Tue/Wed)
- Off-season travel (March, April, October)
- Red-eye or early morning flights
Example: A Thursday flight from Paris to Rome might cost €18, while Friday jumps to €50.
4. Consider Budget Airlines
Europe is home to some of the best low-cost carriers in the world. While they may not offer luxury, they can get you across the continent for under €30.
Top Budget Airlines in Europe:
- Ryanair (Ireland) — Tons of city-to-city routes
- Wizz Air (Hungary) — Best for Eastern Europe
- Vueling (Spain) — Strong Southern Europe network
- easyJet (UK) — Great coverage from the UK and France
Tip: Always check baggage and seat fees. What looks like a €15 flight can turn into €50 with extras.

5. Use Smaller Airports and Nearby Cities
Big cities like London, Paris, and Milan have multiple airports. Smaller or secondary airports often host budget carriers with cheaper fares.
Examples:
- London Stansted (STN) instead of Heathrow (LHR)
- Paris Beauvais (BVA) instead of Charles de Gaulle (CDG)
- Rome Ciampino (CIA) instead of Fiumicino (FCO)
Use filters in your flight search to include nearby airports.
6. Travel Light to Avoid Baggage Fees
Most budget airlines allow only one small carry-on bag for free. Any extra bag, even a rolling cabin suitcase, can cost €20–€40 one way.
Tips:
- Use a personal-sized backpack (check airline size limits)
- Wear your bulkiest clothes
- Skip toiletries and buy at your destination if needed

7. Book Roundtrips or Multi-City Tickets
Sometimes a roundtrip ticket is cheaper than a one-way, especially with legacy airlines. Also, use multi-city search to chain together cheap cities.
Example:
- Fly into Budapest, out of Vienna
- Book Rome → Athens → Madrid in one search
8. Travel in Shoulder Season
May, September, and early October offer great weather in most of Europe without the summer price hikes. Flights are less full, airports are less chaotic, and accommodation is cheaper too.
9. Use Affiliate Tools and Search Widgets (Like Travelupo)
If you’re already on a travel aggregator blog (like this one!), use the embedded flight search tools powered by Travelpayouts, Aviasales, or Skyscanner.
Benefits:
- One-click access to live flight deals
- Filters for budget airlines
- Price comparisons across dozens of platforms
Try searching with your departure city and “Everywhere” to discover cheap routes.
