How to Save Money on Ryanair Flights: A Complete Guide

Understanding Ryanair’s Fare Structure and Hidden Costs

When it comes to budget air travel, Ryanair has become synonymous with low-cost flights across Europe. However, according to recent research by consumer advocacy group Which?, many travelers may be paying more than necessary due to the airline’s complex pricing structure. The investigation, which spanned two years and included around 30 separate fare checks, revealed that Ryanair’s website can be notoriously complicated to navigate, and what appears to be a good deal at first glance might actually cost you more in the long run.

Ryanair operates on a tiered pricing system with six different fare bundles, each offering varying levels of service and amenities. The Basic Fare is the most affordable option, including only a small cabin bag that must fit under the seat in front of you, with no additional baggage allowance and randomly assigned seating. Moving up the ladder, the Regular Fare adds priority boarding, a standard seat, and an additional 10kg cabin bag for overhead storage. The Plus fare expands on this with a 20kg checked bag, while the Family Plus bundle caters specifically to groups traveling with children under 12, offering multiple bag options and free seats for kids. At the premium end, Flexi Plus and Time Saver fares provide maximum flexibility, including the ability to change flights without fees, priority boarding, fast-track security, and preferred seating options. While this tiered system appears straightforward, Which? discovered that purchasing the basic fare and adding extras individually often resulted in significant savings compared to buying pre-packaged bundles, even when Ryanair’s own website suggested higher-tier options as “ideal” for specific trips.

The Basic Fare Strategy: Why Less Might Be More

The cornerstone of Which?’s money-saving advice revolves around starting with the Basic Fare and selectively adding only what you truly need. In one striking example, when booking a family trip for four from London to Alicante in August, Ryanair’s website displayed a banner suggesting that “Regular is ideal for your trip.” However, Which? found that following this recommendation would have cost £59 more than choosing the Basic fare and adding necessary bags and seat selections later in the booking process. This pattern repeated across multiple routes and dates, with the Regular fare proving cheaper than the à la carte approach only once in 15 different flight checks conducted in February 2026.

The Plus fare showed even more dramatic potential savings. For a summer journey from Stansted to Malaga, a family of four could save £35 by selecting the Basic fare and purchasing the equivalent Plus extras separately. If the family determined they didn’t need all the luggage allowances included in the Plus bundle, their savings would increase even further. This finding challenges the intuitive assumption that bundled packages always offer better value. Ryanair strongly disputed these claims, stating that their bundles are dynamically priced and should cost the same as buying the base fare with individual extras added separately. The airline characterized Which?’s findings as “fake news” and insisted their bundle pricing represents the cheapest available fare at the time of booking plus the cost of extras if purchased individually. Despite Ryanair’s rebuttal, Which? stands by its research methodology, which involved systematic price comparisons across numerous routes and dates.

Luggage Rules and Avoiding Expensive Gate Fees

One area where passengers can face unexpectedly high costs is baggage, making it crucial to understand Ryanair’s strict size requirements. If you’ve purchased only the Basic Fare, your single allowed bag must measure no larger than 40cm x 30cm x 20cm and fit completely under the seat in front of you. Should gate staff determine your bag exceeds these dimensions, you’ll face a hefty fee ranging from £46 to £60, depending on your route. The penalties increase even more for cabin bags intended for overhead lockers. If you’ve paid for overhead storage but your bag exceeds the 55cm x 40cm x 20cm limit, you’ll be charged between £70 and £75. These fees can quickly transform what seemed like a budget flight into an expensive journey.

Ryanair defends these charges by pointing out that passengers who comply with the agreed dimensions avoid all fees. The airline also notes that their bag sizers at the airport are actually slightly larger than the permitted dimensions, meaning if your bag fits in the sizer, it will be accepted without charge. This built-in tolerance provides some margin for error, but travelers should still measure their luggage carefully before arriving at the airport. When it comes to checked baggage strategy, Which? suggests that families might find better value in checking one 20kg bag rather than paying for two 10kg cabin bags, though prices vary by route and should be compared on a case-by-case basis. This approach can streamline your airport experience while potentially reducing costs, particularly for family trips where consolidated luggage makes practical sense.

Family Travel and Seating Considerations

For families traveling together, the research revealed that the Family Plus bundle often provides more luggage than most groups actually need, making it a poor value proposition. When Which? priced out a trip for two adults, a teenager, and a four-year-old on the Alicante route, they found that Family Plus was more expensive than necessary for typical family needs. By instead purchasing Basic tickets with seat selection, three 10kg cabin bags, and one larger 20kg checked suitcase, the family would save £45. The Family Plus bundle would have provided each of the four travelers—including the toddler—with a 10kg wheelie suitcase, a share of a 20kg case, and individual small bags, an amount of luggage most families simply don’t require for a standard vacation.

The question of seat selection presents a more nuanced decision. Which? found that passengers who don’t pay for seat selection with Ryanair face a “significant risk” of being separated from their travel companions. Their survey indicated that only 62% of Ryanair passengers were seated next to their loved ones without paying for seat selection. While this represents a “reasonable chance,” it falls short of the near-certainty offered by other budget carriers like easyJet, British Airways, and Jet2, which typically seat groups together even without paid selection. For families with young children or anyone who considers sitting together non-negotiable, paying for seat selection provides peace of mind and guarantees adjacency. Ryanair disputed this characterization, calling the claim false and stating there was no factual basis for suggesting their free seat assignment separated groups more frequently than competitors. Nevertheless, if sitting together is important to your travel experience, the modest cost of seat selection may be worth the certainty it provides.

Additional Money-Saving Tips and Insurance Considerations

Beyond the core fare and luggage decisions, Which? identified several additional areas where travelers can trim costs. The organization’s travel insurance experts strongly advise against purchasing travel insurance directly through Ryanair or most other airlines. Airline-offered insurance policies typically cost more than third-party alternatives while providing less comprehensive or tailored coverage for your specific needs. Dedicated travel insurance providers often offer better value with more extensive protection, including coverage scenarios that airline policies may exclude. Ryanair responded to this advice by stating they don’t particularly care whether passengers purchase the airline’s insurance or third-party coverage, as long as travelers are properly insured—a reasonable position that actually supports the idea of shopping around for the best insurance deal.

Another potential savings area involves currency conversion for international bookings. When booking a ticket that originates overseas for travel into the UK, Ryanair provides the fare in the departure country’s currency. The airline then offers automatic conversion to pounds, but Which? found this service uses unfavorable exchange rates. In their example, a family of four flying from Alicante to London faced a fare of €1,439, which Ryanair converted to £1,321. However, by checking the actual exchange rate on specialized currency conversion sites like xe.com and paying in euros through their bank’s conversion service, the family would have saved £81 compared to accepting Ryanair’s automatic conversion. While Ryanair maintains its conversion rates are competitive and claims indifference about whether customers use the service, the mathematics suggest that travelers with credit cards offering favorable foreign transaction terms will generally save money by declining the airline’s conversion and letting their bank handle the exchange.

The Bigger Picture: Budget Airlines and Informed Travel Decisions

The broader lesson from this investigation extends beyond Ryanair specifically to budget air travel generally. Low-cost carriers have revolutionized European travel by making flights affordable for millions of people, but their business models rely on unbundling services that traditional airlines once included in a single ticket price. This à la carte approach theoretically allows travelers to pay only for what they use, but it also creates complexity that can work against consumers who don’t carefully compare options. Ryanair’s response to the Which? findings was characteristically blunt, dismissing the research as “fake news” and pointing to their passenger growth from 200 million to 208 million in 2025 as evidence that travelers are satisfied with their service and pricing. The airline suggested that no one pays attention to Which?’s “spurious advice,” though the consumer group’s track record of advocacy suggests many travelers do value independent analysis of complex pricing structures.

The truth likely lies somewhere between these positions. Ryanair and similar budget carriers have indeed made travel accessible to people who previously couldn’t afford it, and their basic business model of offering low base fares with optional add-ons serves many travelers well. However, the complexity of comparing bundles against individual purchases, combined with website design that may nudge customers toward higher-priced options, means that less diligent shoppers probably do pay more than necessary. The key takeaway for travelers is the importance of approaching budget airline bookings with a critical eye: carefully assess what you actually need for your trip, compare the cost of bundles against buying items separately, measure your luggage before leaving home, consider third-party insurance, and be mindful of currency conversion rates. By investing a few extra minutes in the booking process to implement these strategies, you can ensure you’re truly getting the budget-friendly flight you’re seeking rather than inadvertently paying premium prices through a series of small charges that add up to significant money.
