For any travel-related issues, the Brussels Airline Barcelona Office is a great resource. My travel itinerary needed to be changed, and the personnel handled it quickly and without charging me extra. They addressed all of my inquiries and were really courteous. I felt completely at ease in the tidy, contemporary office. These days, it is uncommon to get such excellent customer service. I sincerely appreciate their diligence and generosity. I really advise going there if you need any help traveling.
