That is because while IDB can be done at discretion, it violates the law if that discretion is based on racism.
That was what Raed Jarrar alleged and it's why he had standing to bring a case. He wasn't suing because of a breach of the conditions of carriage - he was suing on the basis that a common carrier can't discriminate on race.
A countract is a contract; it has terms. To call it a transaction that can be voided at a whim is to misunderstand the term "contract". In this case, "if [the passenger] was not disruptive under a reasonable construction of the term, he was in compliance with the CoCs and the airline was in breach."* A reasonable construction of a term is not something left to the whim of a CEO; the discretion is limited.

You are wrong.
The contract specifically allows boarding to be denied at the discretion of airline staff, even if that decision appears to be a "whim".
