''Bucharest, Budapest, and Sofia – together with Cluj-Napoca and Sofia – are all in Wizz Air’s top-10 airports. So too are London Luton, Warsaw, Gdansk, Vienna, and Dortmund. Given short runways at London Luton and Dortmund which may well prohibit fully-loaded, 239-seat A321neos to Abu Dhabi, Warsaw and Vienna are possible.''
