Most and Least Expensive Airlines in Europe in 2026

How 2026 Airline Cost Rankings Were Calculated

The latest comparisons of European airfares for 2026 rely less on headline ticket prices and more on what airlines truly earn from each seat they fly. Several recent analyses use passenger revenue per available seat kilometre, often referred to as RASK, to compare 2025 financial data across carriers that operate very different networks. This metric divides the money airlines receive from passengers by the total number of seats and kilometres flown, producing a figure in euro cents per seat kilometre.

Using this approach, consumer platforms and aviation media have ranked more than twenty European airlines from cheapest to most expensive on a comparable basis. One widely cited study covering the 2025 financial year finds a spread of more than 27 euro cents per seat kilometre between the lowest cost operator and the most expensive regional carrier, underlining how sharply prices diverge across the market.

These cost based rankings sit alongside separate benchmarks that look at reliability, hidden fees and customer experience. Taken together, they provide a more rounded picture for 2026 of which European airlines are genuinely inexpensive to fly and which primarily target higher yielding passengers.

The Cheapest Airlines in Europe in 2026

Across multiple 2026 comparisons, Hungary based Wizz Air emerges as the cheapest airline in Europe on a pure cost per seat kilometre basis. Data compiled from 2025 results indicate that Wizz Air generated about 4.33 euro cents of passenger revenue per available seat kilometre, edging out rivals to retain the top position for a third consecutive year in at least one ranking.

British carrier easyJet typically appears in second place among the lowest cost airlines, with an average RASK a little above 5 euro cents per seat kilometre. Analysts point out that easyJet reduced its revenue per seat kilometre significantly between 2024 and 2025 while maintaining broad network coverage, which helps explain its strong showing in the 2026 lists of budget friendly carriers.

Ryanair, one of Europe’s largest airlines by passenger numbers, usually occupies third position in these cost tables. Available figures show its passenger revenue per seat kilometre falling from roughly 8.4 euro cents in 2024 to around 5.6 euro cents in 2025, making it one of the most improved airlines year on year in terms of pricing.

Behind these headline names, a mix of hybrid and full service operators appear in the cheaper half of the European ranking. Finnair, Transavia, Norwegian Air Shuttle, TAP Air Portugal, Iberia and Turkish Airlines all post RASK figures broadly in the 6 to 7 euro cent range, placing them closer to the budget carriers than to the most expensive national airlines.

Europe’s Most Expensive Airlines by Seat Kilometre

At the other end of the RASK table, several familiar flag carriers sit among Europe’s most expensive airlines in 2026. For these operators, higher average fares reflect a combination of premium cabins, dense business markets, higher cost bases and, in some cases, relatively short sectors that push up the revenue per seat kilometre figure.

Recent coverage of European pricing data highlights British Airways as the most expensive large national carrier in the region. The airline’s passenger revenue per available seat kilometre reached about 8.88 euro cents in 2025, an increase compared with the previous year. That places it above competitors such as Lufthansa, Air France, Swiss and Austrian Airlines, which cluster around 8.3 to 8.5 euro cents per seat kilometre.

Among the carriers included in the same ranking, Austrian Airlines and Air France report similar average revenue per seat kilometre of about 8.5 euro cents. Lufthansa’s figure sits slightly lower at around 8.45 euro cents, while KLM, ITA Airways and Swiss are positioned just below that band. These results suggest that travellers choosing Europe’s traditional network airlines can expect broadly comparable pricing, with British Airways currently at the top of the scale.

One outlier is Norwegian regional carrier Widerøe, which records a revenue per seat kilometre figure above 30 euro cents, reflecting its focus on short, thin routes in challenging geography rather than mainstream European trunk markets. For most leisure travellers comparing options across major hubs, the practical distinction lies between the roughly 4 to 6 euro cents charged by ultra low cost airlines and the 8 to 9 euro cents typical of large full service carriers.

Gaps Are Widening Between Low Cost and Legacy Carriers

The 2026 data underline a wide and, in some cases, growing gap between Europe’s cheapest and most expensive airlines. The difference between the lowest RASK in the ranking and the highest reaches nearly 28 euro cents per seat kilometre. Even if many travellers do not think in terms of cost per kilometre, aviation analysts note that such a spread translates into substantial differences on longer routes.

Industry reports for 2025 and early 2026 show that many low cost airlines managed to reduce their passenger revenue per seat kilometre compared with the previous year, despite strong travel demand. Ryanair and easyJet stand out for significant declines in RASK, while Wizz Air kept its figure low even after a modest increase. In total, more airlines in the ranking recorded lower average prices than higher ones year on year.

By contrast, several traditional European flag carriers saw their RASK figures edge up as they continued to rebuild long haul capacity and focus on higher yielding segments. British Airways and Air France both reported small increases in revenue per seat kilometre, while KLM and some other network airlines posted slight rises. This divergence suggests that low cost competitors are still using aggressive pricing to capture leisure demand, while full service airlines lean more heavily on business travellers and premium cabins.

Broader industry analysis from organisations such as Eurocontrol and IATA points to easing fuel prices and strong demand helping European airlines improve profitability through 2025. However, higher labour and airport costs, along with new environmental charges on emissions, are feeding into fares. How efficiently each airline manages these pressures appears to be a key factor in where it lands on the 2026 cost ranking.

What the 2026 Rankings Mean for Travellers

For travellers planning European trips in late 2026 and into 2027, the latest numbers offer clear signals about where to look for the lowest base fares. Wizz Air, easyJet and Ryanair currently anchor the bottom of the cost per kilometre table, giving price sensitive passengers a starting point when comparing itineraries. Other relatively low cost names such as Transavia, Vueling, Norwegian and Eurowings provide additional options on specific routes.

Travel specialists caution, however, that RASK figures capture average revenue per seat kilometre rather than the full experience or final amount paid by an individual passenger. Fees for baggage, seat selection, payment methods and airport services can reshape the real cost of a given trip, especially on low cost airlines that rely heavily on ancillary charges. Separate 2026 comparisons that track total trip costs across sample routes show that once standard luggage and seating are included, some full service or hybrid airlines can become competitive with headline low cost operators.

For travellers considering the more expensive national airlines, the 2026 data suggest that British Airways currently sits at the higher end of the European price spectrum, with other major flag carriers grouped slightly below it. Passengers often weigh these higher average fares against network breadth, frequent flyer benefits, connection quality and cabin comfort, which are not reflected directly in revenue per seat kilometre metrics.

Ultimately, the 2026 rankings reinforce the importance of comparing complete itineraries rather than relying solely on brand reputation or marketing fares. RASK based tables, real world fare trackers and reliability benchmarks together provide a more transparent view of how Europe’s airlines are pricing their services, helping travellers decide how much they are willing to pay for convenience, comfort and flexibility on their next flight.
