Thank you. If there is no FFP that allows me to exchange avios for small worthless gifts I will keep Iberia Plus. I'm expecting that this trip will be the only one where I will pass thru Doha duty free shop.
The credit cards are a good way to maintain avios but the one that have miles reward usually have a higher anual fee. I had amex, it was expensive, and the one from miles&more credit card also has an expensive fee.
