Wizz Air is a Hungarian ultra-low-cost carrier founded in 2003 and headquartered in Budapest, Hungary. It operates an extensive network across Central and Eastern Europe, as well as routes to Western Europe, the Middle East, and beyond, making it one of the fastest-growing airlines in Europe. The airline is known for its no-frills model, charging low base fares while offering optional paid extras such as checked baggage, seat selection, and priority boarding. Wizz Air has been recognized for its relatively young, fuel-efficient fleet and its focus on secondary and regional airports to reduce costs. Wizz Air is publicly listed on the London Stock Exchange and has expanded its operations through subsidiaries including Wizz Air Abu Dhabi, a joint venture launched in 2021 to serve routes from the United Arab Emirates.
