Ryanair DAC is an Irish ultra low-cost airline founded in 1984. It is headquartered in Swords, Dublin, with its primary operational bases at Dublin and London Stansted airports. It forms the largest part of the Ryanair Holdings family of airlines, and has Ryanair UK, Buzz, and Malta Air as sister airlines. In 2016, Ryanair was the largest European budget airline by scheduled passengers flown, and carried more international passengers than any other airline.
It follows Minsk's move to divert a Ryanair passenger plane and arrest dissident journalist Roman Protasevich last month.
