Air Miles are a type of loyalty program that allows travelers to earn points or miles for flights and other purchases. These points can be accumulated through flying with specific airlines, booking hotels, or using certain credit cards. Once enough points are collected, they can be redeemed for free flights, upgrades, or other travel-related rewards. Many airlines and travel companies offer their own versions of Air Miles, making it easy for customers to choose the program that best fits their travel habits. Participants can often track their miles online and receive special promotions to help them earn even more points.
