Not quite so straightforward, I'm afraid.
If the offer arises from a mechanical error of arithmetic and the other party is viewed as "snatching up" the offer, the contract will be voidable.
You could take BA to court to see if the judge upholds the contract, but if instead he agrees that the contract is voidable on those grounds and you lose, expect a much bigger bill than 600EUR for costs.
