If you disagree with DY's or SK's rebookings, then I think that the idea is that you arrange the rebooking yourself by buying a ticket for some flight and then ask the airline to compensate you for this, suing the airline if they won't pay. However, it's very dangerous as you may lose in court and then you won't only have to pay for the new ticket but also for the airline's legal fees.
