The Ryanair Group (Ryanair Holdings PLC) is the parent company of five distinct subsidiary airlines in 2026, each operating under its own brand but sharing a unified low-cost business model. These include Ryanair DAC (the original Irish carrier), Buzz (the Polish-based subsidiary), Lauda Europe (based in Malta, focusing on Mediterranean routes), Malta Air, and Ryanair UK. This "multi-brand" strategy allows the group to navigate different labor markets and regulatory environments across Europe while maintaining the massive scale needed to keep fares low. In 2026, the group remains the largest airline entity in Europe by passenger volume, utilizing a standardized fleet of over 600 Boeing 737 aircraft. While the planes may have different logos on the tail—such as the Buzz bumblebee or the Malta Air red-and-white—the "Ryanair" core service, including strict baggage policies and digital-first check-in, remains identical across all five sister airlines, ensuring operational efficiency across their vast 220-airport network.
