Consumers used to select a credit card based on interest rates and credit limits. These days, consumers are applying for credit cards for the add-on perks offered. Airline charges is one area currently being targeted by many credit card companies.

American Express is one example of a company using reduced airline fees as an attractor. Card holders can apply for rewards covering baggage fees, change fees, pet fees, and in some cases, on-board snacks. Other credit cards can help with access to the airport lounges or provide elite boarding options.
