Europes top budget airlines have begun shifting their flight routes from Sweden to Denmark as a result of the progressive reduction of passenger departure taxes at Copenhagens international airport. AirBerlin, Europes third biggest budget flights operator, started flying out of Kastrup in May, and is already offering over 20 destinations including Rome, London and Vienna. Package tour operators including Swedish travel company Fritildsresor are also planning to move their departures to Copenhagen airport. Irish low-cost airline RyanAir, Swedish FlyMe and Hungarian Wizzair look set to follow suit. The Danish tax drop coincides with Swedish plans to impose a duty on flying.
