You may have heard of frequent flyer programs, where participants earn points which award free airfares and benefits not available otherwise. But did you know that you do not have to actually fly in an airplane to earn these rewards?There are many credit card companies today which offer customers the benefit of frequent flyer points. These credit cards have a special partnership with designated airline companies, awarding points to consumers based on certain types of purchases, cash advances, or other transactions. By making regular, everyday purchases, cardholders receive additional points. Different cards will offer different benefits or incentives. Participating cardholders commonly earn one or two free airline tickets every year.Airline frequent flyer rewards credit cards come in two distinctive types. The first type of card is issued through an affiliated airline carrier, and is a good option for those who travel often. These cards are also wonderful for those who fly regularly for business purposes. If you have a tendency to use different airlines, or if you do not travel often, then you would be wise to choose the second type of card, which awards all-inclusive points. With this type of card, you will be allowed to use your frequent flyer points for travel on any airline, rather than being obligated to any one particular airline company.Most major credit card companies offer frequent flyer incentive programs. For example, American Express offers a credit card with no expiration date on corresponding airline points, with double rewards for dining, travel, leisure, or entertainment purchases. A card through Bank of America offers no black out dates and rewards for all types of purchases. Visa, MasterCard, and Discover cards also have numerous cards through various companies, many of which also offer frequent flyer incentives.
