Their discount '$9 club' program. They 'autorenew' without any advanced notice, charging a non-refundable 69.95 on accounts used in the previous year. I never agreed to a 2nd year. There are many things a company can put in their fine print to take advantage of customers. This scheme is particularly egregious. They would not even prorate. This is a deceptive, malicious act on the part of Spirit Airlines. Spirit Airlines is most likely taking advantage of thousands of Americans who will not bother to take Spirit Airlines to court for a $70.00 charge on their account. Spirit claims that since this is in their fine print, credit card companies are not allowed to dispute the charge. Stay away from this deceitful company.
