Avios is a rewards scheme that is linked to airline frequent flyer clubs. Avios credit cards work in a very similar way to supermarket loyalty cards, such as Nectar and Tesco Clubcard. The value of your Avios points varies depending on how and where you spend them. They don't have a fixed value. Sometimes they’re worth more if you’re taking advantage of a special promotion. You can move or combine Avios points from different sources in order to build up enough to exchange for flights, holidays and other things.
