Cash-back credit cards can also help you save big on cruises, provided you can redeem your points for statement credits or gift cards for cruise lines. We love the
Chase Freedom because you can earn 5 percent back on up to $1,500 in spending in categories that rotate each quarter, plus 1 percent back on everything else. You can redeem your points for cruise line gift cards, statement credits, or travel through the Chase Ultimate Rewards portal.
