It wouldn’t be the best idea to rely on your credit card company to cater for your rental damages unless they provide you a policy that can guarantee their commitment to settling the fees with your rental agency (preferably in Spanish). Typically, your card provider won’t cover damage costs, and even if they do, they’ll reimburse the funds after a while. That means that you'll have to cater for the charges from your personal account unless they issue a confirmation that they’ll settle the matter with your car rental at Santa Maria Airport.
