Airline rewards are loyalty programs offered by airlines to encourage frequent flying. Members earn points or miles for each flight they take, which can be redeemed for free flights, upgrades, or other travel-related benefits. These programs often have different tiers, allowing members to unlock additional perks as they accumulate more points. Many airlines partner with hotels, car rental companies, and credit card providers, enabling members to earn rewards through various purchases. This flexibility allows travelers to maximize their points and enjoy a range of benefits, making travel more affordable and enjoyable.
