Brussels Airlines has made this announcement:
Because of the rapidly declining demand in air travel within Europe, Brussels Airlines had already taken the decision to reduce flight frequencies on a number of routes in Italy in order to limit the negative economic impact on its business. Next to the already cancelled 30% of its flight frequencies to and from Milan Linate and Milan Malpensa, Venice, Rome, Bologna and Turin between March 2 and 28, the Belgian airline now further reduces its flight offer to and from Italy as well as within the rest of Europe between March 8 and 28. In total, the airline reduces its flight offer within Europe by 23%.
Passengers whose flight is cancelled are being contacted and rebooked on other available flights or they can choose to get a full refund, if they do not wish to travel anymore.
