If you don't travel often, you might not be aware of the perks that your card offers travelers. Here are a few that can ease your wallet.

No currency conversion fees. Many cards levy them, and these fees can add 1 percent to 3 percent to everything you buy overseas. A credit card that doesn't charge a foreign transaction fee can save you a bundle.

Trip cancellation insurance. This feature covers your losses if you have to cancel a trip, often due to illness or injury. However, issuers will have specific rules about what does and doesn't qualify for your reason and how much you will recoup.

Travel assistance. You've run into some problems abroad and need assistance, medical care or legal help. Some cards will step in and provide or coordinate resources. But what they offer varies widely with the card. With some cards, you must have put trip expenses on the card to qualify.

Coverage for Murphy's Law. Cards for travelers often offer lesser-known perks aimed at providing some "peace of mind," says Danielle Fagre Arlowe, senior vice president of state government affairs for the American Financial Services Association. Look for benefits such as lost luggage reimbursement, travel accident insurance and car rental insurance.
