Spanish airline Vueling announced it will fly between Rotterdam (RTM) and Barcelona (BCN) airports from April 2015. Flights will take place four times a week: on Monday, Wednesday, Friday and Sunday. Flights are already bookable at http://www.vueling.com. The Vueling flights come on top of those carried out by Dutch airline Transavia (of the Air France-KLM Group), that connect the two cities four times a week already. The frequency of Transavia’s flights will be increased to 6 or 7 per week during summer 2015. The abundance of cheap flights between RTM and BCN will contribute to the growing tourist and business links between the metropolitan area of Barcelona (5,4 million people and the capital of independence-minded Catalonia) and the metropolitan region of Rotterdam-The Hague (2,5 million inhabitants and combining the largest port on the Atlantic with the political capital of the Netherlands).
