Dear customers We're sorry you could not enjoy the Sky Tour over the City of Barcelona, as you have commented, you could not fly over Barcelona due to the Notam published by Civil Aviation as a result of the political occurrence, protests, etc. that were there in the City when you came. As of today, November 5th, cannot be overflown yet. As you said they offered you the alternative flight or reimbursement. The alternative Flight can never be the same as the City Tour because that Tour cannot fly above the city, but you can fly along the seashore and the Besos River that is the periphery of Barcelona where you can enjoy an amazing’s City views too.
