Want to know how an upgrade Costa cruise booking works? Costa Club members who meet the applicable requirements may be entitled to an Upgrade or SuperUpgrade on qualifying cruises. The benefit is subject to cabin availability and must be checked before booking or applied according to the current programme rules. Depending on the member level and purchased cabin, the upgrade may provide access to a higher category without changing the price of the originally purchased cabin. Not every cruise qualifies, and guaranteed cabins may be excluded from the privilege. For more information, call 888-653-0010.
