Rights in cases of denied boarding
If passengers are denied boarding on the flight they have booked – for example due to overbooking – they are entitled to a compensation payment of €250 to €600. The amount of compensation depends on the distance of the flight. This compensation must be paid in cash or by bank cheque. Passengers need not accept flight vouchers, air miles or upgrades that the airline might offer them.
However, passengers are only entitled to compensation if they do not give up their reservation voluntarily on the flight they have booked.
