Europe’s deregulated aviation market has transformed continental travel into an affordable adventure, with budget airlines offering flights between major cities for as little as $20-50. Whether you’re planning a multi-city European adventure or a quick weekend getaway, knowing how to navigate the complex world of European aviation can save you hundreds of dollars.
Best Budget Airlines in Europe: The Ultimate Comparison
Top Low-Cost Carriers by Affordability
Wizz Air consistently ranks as Europe’s cheapest airline, with an average revenue per seat kilometer of just €0.0398. According to our research, European airlines don’t come any cheaper than Wizz Air, and by a fairly wide margin. Operating over 800 routes from 32 bases across 16 countries, Wizz Air connects nearly 200 destinations throughout Europe and beyond.
Ryanair remains the undisputed king of European budget travel, serving over 200 destinations in 34 countries. Ryanair routinely flies from London to any one of dozens of European cities for less than $30 during promotional periods, though additional fees can quickly add up.
EasyJet offers a more premium budget experience, operating from major airports rather than remote secondary hubs. Unlike most budget carriers, easyJet operates from main airports. So, while its fares might be slightly higher than Ryanair’s, the easy airport access is a huge plus.

When to Book: Timing Strategies for Maximum Savings
Optimal Booking Windows
For International Flights to Europe: CheapAir’s annual study of 917 million airfares revealed that the best time to buy a flight to Europe is 10.5 months in advance. But you can find deals throughout the prime booking window, which is between 6 weeks and 10 months ahead of time.
For Flights Within Europe: The best time to book a short-haul flight is a few weeks to four months before departure. European budget airlines frequently run flash sales, making flexibility your greatest asset.
Seasonal Price Patterns
Cheapest Travel Months:
- October to March – Off-season offers the best deals
- January – Going found the most deals with travel dates in January.
- Late August – U.S. travelers can save up to 30 percent on flight tickets by flying in mid-August instead of early July.
Most Expensive Periods:
- June-July – Peak summer season
- Christmas/New Year – Holiday premium pricing
- Weekends – Saturday is typically the most expensive day to fly
Weekly Booking Patterns
Tuesday, followed closely by Wednesday, is the cheapest day to fly on average. Unsurprisingly, Saturday ranked as the most expensive day of the week to fly to Europe. Mid-week flights consistently offer better value than weekend departures.
Essential Flight Search Tools and Platforms
Primary Flight Comparison Sites
Google Flights emerges as the top choice for comprehensive European flight searches. It’s uncluttered and easy to use, with excellent results for both intercontinental and intra-European flights on a combination of mainstream and budget carriers. Its calendar view and price tracking features make it invaluable for flexible travelers.
Skyscanner specializes in European budget airlines and provides excellent overview capabilities. My first stop when seeking budget flights within Europe is Skyscanner; this straightforward website specializes in European budget airlines and gives an overview of all of my options.
Momondo offers visually engaging price comparisons and flexible date searches, particularly useful for finding deals across multiple European destinations.
Advanced Search Strategies
Multi-City and Open-Jaw Tickets: Consider booking separate one-way flights to different European cities, especially if you’re planning an extended trip. You can also opt to book the cheapest one-way flights you can find to and from Europe and travel in between those cities.
Nearby Airport Options: Budget airlines often use secondary airports. Some of Ryanair’s flights to “Frankfurt” actually take you to Hahn, 75 miles away. The savings often justify the extra travel time to city centers.
Money-Saving Strategies and Expert Tips
Booking Tactics That Work
Advance Planning: It’s wise to start looking for international flights at least four to six months before your trip, especially for travel in spring, summer, or fall. However, good deals on winter travel (November through March) can usually be purchased a month or so in advance.
Flexibility Is Key: Be flexible and use tools like price alerts and the “everywhere” or “explore” features to find the best flight prices. Use flexible date searches to identify the cheapest travel periods.
Price Monitoring: Set up alerts on multiple platforms. Tools like Google Flights and Hopper’s “Watch This Trip” can help you track the price of your desired route before booking and notify you when prices are lowest.
Budget Airline Fee Management
Baggage Strategy: If you plan to check a bag, pay the fee when you purchase your ticket — on many budget airlines, the price per bag gets progressively higher the closer you get to your departure.
Carry-On Compliance: European budget airlines often have stricter size requirements. Don’t assume your bag qualifies as carry-on in Europe; many budget airlines use smaller dimensions than other carriers.
Early Check-In: They normally allow you to check in 30 days before a flight and I suggest you take advantage of it because they’ve overbooked my flight twice during peak season.
Alternative Route Strategies
Hub-Based Searches: Most budget airlines focus on particular hubs. When looking for cheap flights, first check airlines that use either your starting point or your ending point as a hub.
Connecting Flights: Consider linking a couple of cheap flights, either with the same or different airlines, to reach your destination. But be careful to leave plenty of time for connections.
Popular Routes and Destination Insights
Gateway Cities for Europe
London Heathrow (LHR) and Paris Charles de Gaulle (CDG) serve as primary European hubs. If you’re headed to Europe, consider flying into Reykjavik Keflavik Intl airport in Reykjavik for the best deals, with an average airfare of $123. Alternatively, London Heathrow airport in London is a close second for cheapest flights to Europe with an average airfare of $129.
Budget-Friendly European Destinations
Within Europe Flight Costs: Budget airlines typically offer flights between major European cities for $50–250. While getting overseas is expensive, flying from one European country to the next is actually quite cheap; fares are frequently less than $50.
Eastern European Value: Cities like Budapest, Prague, and Warsaw often offer exceptional value for both flights and accommodations, making them ideal starting points for budget European adventures.
Advanced Booking Strategies
Technology and Tools
Price Prediction Apps: Hopper analyzes 80 trillion flight prices to recommend optimal booking times. Travel booking site Hopper — which relies on 10 years of data and 80 trillion flight prices to recommend the best time to book routes and dates — says the general rule is to book flights between 25 and 150 days prior to takeoff.
Credit Card Rewards: Using credit card rewards is a great way to earn free or discounted flights. Consider travel-focused credit cards that offer bonus points on travel purchases and sign-up bonuses.
Last-Minute Options
While advance booking typically offers the best prices, some charter airlines buck this trend. One option worth checking for last-minute flights if you’re in Europe is charter airline TUI. They buck the trend and often put deep discounts on flights less than 3 weeks away, mostly to beach-type destinations in the Caribbean and Europe.
Safety and Reliability Considerations
Budget Airline Safety Standards
All licensed European budget airlines meet strict European safety standards. If you’re flying with a licensed European budget airline, you can feel confident that your flight meets high safety standards. EU consumer protection laws also provide robust coverage for travelers.
Service Expectations
Budget airlines operate on a “pay-for-what-you-need” model. Budget airlines, also known as low-cost carriers, operate with a no-frills business model. These airlines offer significantly cheaper fares than traditional airlines by stripping away extras like checked baggage, in-flight meals, and seat selection.
Conclusion: Your Path to Affordable European Travel
Finding cheap flights in Europe requires a combination of strategic timing, flexible planning, and smart tool usage. By booking 3-6 months in advance for international routes, remaining flexible with dates and airports, and leveraging the competitive European budget airline market, travelers can save hundreds of dollars on airfare.
Remember that the cheapest seats sell out fast (aside from occasional surprise sales), so when you find a good deal that meets your needs, don’t hesitate to book it. The money saved on flights can significantly enhance your European adventure, allowing you to experience more destinations, better accommodations, or simply extend your stay.
Start monitoring prices early, set up alerts on multiple platforms, and embrace the flexibility that makes European budget travel so rewarding. With over 40 budget airlines serving hundreds of routes across the continent, your dream European adventure is more affordable than ever.
