Buzz

Buzz (ICAO: RYS) is a Polish low-cost airline operating as a subsidiary of the Irish Ryanair Holdings. The current iteration of Buzz was rebranded from Ryanair Sun in 2019 and primarily conducts scheduled and charter flights across Europe.

Buzz was originally a British low-cost airline founded in 1999 as a subsidiary of KLM, commencing operations in January 2000. It was later acquired by Ryanair in April 2003 and ceased operations by October 2004. The name "Buzz" was revived in 2019 when Ryanair rebranded its Polish subsidiary, Ryanair Sun, to Buzz. Ryanair Sun itself was established in 2017, initially focusing on charter flights. Buzz is now one of four airlines within the Ryanair Holdings Group, alongside Ryanair DAC, Ryanair UK, Malta Air, and Lauda Europe.

The airline is headquartered in Warsaw, Poland, and operates with multiple bases across Central and Eastern Europe. These operational bases include Bratislava, Budapest, Gdańsk, Katowice, Kaunas, Kraków, Poznań, Prague, Riga, Sofia, Vilnius, Warsaw–Modlin, and Wrocław. Buzz primarily operates a modern fleet consisting of Boeing 737-800 and Boeing 737 MAX 8-200 aircraft. As of late 2025, the Ryanair Group continued to expand its fleet, with new Boeing 737 MAX deliveries assigned to Buzz. The airline's route network encompasses both scheduled flights on behalf of its parent company, Ryanair, and charter flights to popular holiday destinations throughout Europe. It focuses on countries like Poland, Czechia, Hungary, and Bulgaria, with aspirations to expand to regions such as the Canary Islands, Morocco, Italy, Spain, Turkey, and Greece. Buzz is not a member of any major airline alliance. It offers a single cabin class, Economy Class, and its baggage policy does not include a free checked baggage allowance.
