Air miles, also known as frequent flyer miles or travel points, are a type of loyalty currency earned through airline reward programs. Travellers accumulate air miles by flying with participating airlines, using co-branded credit cards, or making purchases with program partners such as hotels, car rental companies, and retail brands. These miles can then be redeemed for flights, seat upgrades, airport lounge access, or even non-travel rewards like merchandise and experiences.

Most major airlines operate their own mileage programs, often within global airline alliances that allow travellers to earn and redeem miles across multiple carriers. The value of air miles varies depending on the airline, route, and demand, with long-haul and premium-class redemptions typically offering the best value. Understanding how air miles work can help frequent travellers maximize their benefits, reduce travel costs, and enjoy exclusive perks while flying.
