The 10 Largest Airlines in Europe 2026

The King of Low-Cost: Ryanair remains the undisputed leader. In 2025, it became the first European airline to carry over 200 million passengers in a single year—more than the combined populations of Germany, France, and the UK. Despite challenges like French ATC strikes affecting over 30,000 passengers in mid-2025, its growth via subsidiaries like Buzz, Malta Air, and Lauda Europe is unparalleled.

The Powerhouse: Founded in 1926, Lufthansa is a pillar of European aviation. The group now includes Austrian Airlines, Swiss, Brussels Airlines, Eurowings, and a 41% stake in ITA Airways. As a founding member of Star Alliance, Lufthansa continues to lead in premium service and technical innovation from its hubs in Frankfurt and Munich.

Strategic Fusion: Formed in 2011 by the merger of British Airways and Iberia, IAG has become a global force. The group also owns Aer Lingus, Vueling, and LEVEL. A standout success is their loyalty program, IAG Loyalty (Avios), which grew by 38% recently, proving highly popular among younger travelers for lifestyle rewards.

The Heritage Giant: This holding company unites the national carriers of France and the Netherlands. KLM remains the oldest airline in the world operating under its original name. Recently, CEO Ben Smith reinforced trust in their fleet by highlighting rigorous safety standards that exceed industry norms.

From Two Planes to a Giant: Starting in 1995 with just two leased Boeings, easyJet now operates over 300 aircraft. Their expansion through acquisitions has created powerful subsidiaries like easyJet Europe (based in Vienna) and easyJet Switzerland.

The Global Connector: Turkish Airlines flies to 131 countries—more than any other airline. In 2025, it was voted "Best Airline in Europe" by Skytrax for the tenth consecutive year. They are currently rolling out free, high-speed Wi-Fi across their entire fleet to maintain their competitive edge.

The Hungarian Success Story: A newcomer since 2003, Wizz Air has disrupted the market with its low-cost model. However, 2025 brought challenges: roughly 20% of its fleet was grounded for up to 300 days due to mandatory Pratt & Whitney engine inspections. Despite this, their expansion into the Middle East remains a core strategy.

The Premium Icon: Based at London Heathrow, BA serves over 200 destinations. In 2025, they completed a massive upgrade of their Club World suites, offering fully enclosed business-class cabins on nearly all transatlantic routes.

The Great Transition: 2024/2025 marked a turning point as SAS left the Star Alliance to join SkyTeam, following a major investment by Air France-KLM. They recently launched their largest summer schedule ever, adding 28 new routes and increasing capacity by 40% on key routes.

The Red-Nose Comeback: After scaling back long-haul ambitions, Norwegian has refocused on being Europe's leading low-cost carrier for short-haul. They are famous for being the first to offer free Wi-Fi on most European flights—a rarity in the budget sector.
