Thank you, as this is a weakness it would be very timely to correct.
As you have noticed, my questions are always in solution mode.
According to passenger advocacy groups that have appeared before us, the victims of the situation, that is to say passengers, have to prove that they are entitled to compensation and that what the airline has claimed is false. This makes no sense.
In the context of your studies and thinking, is there any possibility of shifting the burden of proof from the air passenger to the carrier?
