Flights tickets are unique compared to TVs etc in the way they make people organize their lives (like hotels, relocating etc). And as the contract is the basic fundament of the society (contrate de social, concept of marriage, and all forms trade etc etc) there must be strict rules to unilaterally cancel any contract. By all means do cancel but pay damage (= also benefit of trade).

There are some contracts that should be harder to cancel to keep the publics trust in the instrument. Could be cash, cheques, e-tickets etc.
