Vueling, a Spanish budget airline, has begun flying from Belfast City Airport today.The maiden flight from London to Barcelona will strengthen the IAG network. Both Aer Lingus (British Airways) and British Airways have a number routes in place.Vuelings offers a flight change policy that allows passengers who book Optima and Family Fare tickets to cancel their flights or modify their plans for no additional cost.It is a good idea to verify the most recent entry requirements before you travel, as Spain is on the government's amber list that requires quarantine upon return.Katy Best, Northern Ireland's airports commercial director, stated: Vueling Airlines will be adding Belfast City Airport to its network of airports this summer. This will give passengers more options and increase the number of European and UK destinations that can be reached from the airport.Vueling has convenient flight times and a twice-weekly service that takes you to this popular Spanish city. We are confident that customers will enjoy the great prices and excellent customer service and have a wonderful time.
