Hotel or travel points credit cards

This is a genre of credit cards specific to hotels and travel. Some cards are co-branded with hotels, such as the Marriott Rewards Visa card, or the Hilton HHonors American Express card. These credit cards allow you to earn points for all purchases, in addition to bonus points for dollars spent on stays at the respective hotel chain. You can redeem your points for free nights and upgrades at the hotel chain your card is co-branded with. 

Then there are broader hotel and travel cards such as the Bank of America's MilesEdge Visa, with which points can be redeemed for travel, theme park admission, stays at major hotel chains and more. Blue Sky from American Express is similar -- points can be applied toward plane tickets, hotel stays, rental car use or cruises. 

Because these reward programs can be costly for credit card companies, many of these cards come with an annual fee. If you are not a frequent traveler, the annual fee may negate the benefit of the rewards earned. Compare hotel/travel points credit cards.
