As I was on business trip, my company bought me a ticket. Who should apply for “cancelled flight compensation UK” in this case?

You are the person who has the right to claim for the cancelled flight compensation, because you are the one who experienced flight disruption, no matter who paid for the ticket – your boss, your parents or someone else. Of course other conditions included in EU 261, such as arrival to destination must be more than 3 hours late and other, must be fulfilled. For more information, please, visit Cancelled Flight Compensation and it is possible to check with our Compensation Calculator how much you are entitled to compensation.
