The base will open next March with six new routes to Pisa, Gran Canaria, Dalaman, Antalya, Marrakech and Enfidha.
The announcement, made alongside the airline’s half year results, is confirmation of the airport’s popularity with the airline which has operated an aircraft there since 2012.
In the past 12 years, the airline has flown more than seven million customers to destinations including Amsterdam, Geneva, Faro, Palma, Malaga and Paris.
