If you plan to travel abroad, be aware your credit card company may levy surcharges on foreign purchases you make. These travel fees are typically about 3 percent of the purchase price.
To avoid some of these travel fees, consider prepaying your international hotel and car rental costs while you're still in the U.S. Also, consider using a credit card that doesn't charge extra for currency conversions and spending overseas. Some card issuers, including Capital One, offer this benefit.
