Earlier this month, Tesco announced Aer Lingus as its new Clubcard rewards partner, promising cheaper flights for shoppers. Under the Aer Lingus scheme, this will translate to 21,600 Avios points – but what can you do with that? Every time you buy a flight with Aer Lingus – or its partners, American, British Airways and United – you will earn points. You could also consider buying or gifting Avios points, earning up to 47 Avios points per €1 spent this way. And you can also earn points with Aer Lingus’ reward partners.
