On the possibly very large assumption that the CSR has it right, I would think you'll win and deserve to win as well. If the credit card company has, as part of its terms and conditions with its merchants, that they must reveal all penalties up front, and the airline has not, you deserve a refund. The fact that you did not ask how much the penalty was is neither here nor there, imho.
