Fly LEVEL SL, trading as Level, is an airline brand under which airlines owned by the International Airlines Group operate low-cost flights. The brand has a registered office in Madrid, Spain. Level was marketed initially as a low-cost, long-haul carrier, and began transatlantic services from Barcelona–El Prat Airport in June 2017. In July 2018, Level expanded with long-haul services from Paris Orly Airport which took over the operation of IAG subsidiary OpenSkies, and began its first short-haul services from Vienna International Airport, operated by Level Europe. On 18 June 2020, Level Europe entered insolvency and the brand’s short-haul flights operated by the Austrian-based airline were terminated with immediate effect. On 8 July 2020, the shutdown of OpenSkies was announced and initially ended the brand’s long-haul flights based at Paris Orly, and although ticket sales for OpenSkies flights under the brand were later restarted, operations did not resume.
