Iberia have a very generous 50% campaign for Avios redemptions. You will need to modify your account details if your details do not match the eligibility requirements.
Iberia have a specific reward chart for redemptions on their own flights. This post also helps you identify some sweet spots for maximum efficiency and value for money.
Deliveroo has an Avios promotion running through the whole summer for UK residents. This may be good if you want food or drink sent to you instead of ordering a takeaway!
This page shows the off-peak and peak Avios redemption dates for British Airways and Iberia for 2017 and 2018. Note the differences between the two systems!
British Airways, Iberia, LAN Airlines and TAM Airlines may soon be code sharing Transatlantic flights between Europe and South America. Could we be seeing more opportunities for air miles?
