Flyer points, also known as frequent flyer miles or loyalty program points, are a type of reward earned by customers for their purchases or activities related to an airline, hotel, credit card company, or other businesses. These rewards can be accumulated over time and then redeemed for various perks such as free flights, upgrades, hotel stays, rental cars, merchandise, or even cash back. The number of points earned varies depending on the specific program rules and the type of activity involved (e.g., flying, shopping, dining).
