If the flight is cancelled, they will put you on the next available flight. They have to offer you a) your money back and compensation (you void your entire ticket) or b) compensation and a seat on the next flight.

The airline will most likely fly anyway, it could be more expensive to keep the flight on the ground as they have a return segment to operate as well.

Does it mean that passengers with valid tickets are entitled to flight - the airline cannot just give full refund plus compensation and not fly the passenger at all, even if they want to?
