Today the European Commission reaffirmed not only the right to a refund, but also the right to be reaccommodated at another time on the original route, for no extra money:
Under EU rules, travellers have the right to choose between vouchers or cash reimbursement for cancelled transport tickets (plane, train, bus/coach, and ferries) or package travel. While reaffirming this right, the Commission's recommendation aims to ensure that vouchers become a viable and more attractive alternative to reimbursement for cancelled trips in the context of the current pandemic, which has also put heavy financial strains on travel operators. The voluntary vouchers should be protected against insolvency of the issuer, with a minimum validity period of 12 months, and be refundable after at most one year, if not redeemed. They should also provide passengers sufficient flexibility, should allow the passengers to travel on the same route under the same service conditions or the travellers to book a package travel contract with the same type of services or of equivalent quality. They should also be transferable to another traveller.
