I recommend that you choose the card that offers the most perks to you. Each person will be different in their opinion of which of these perks are the most valuable, depending on which airline they're loyal to.Personally, I would rank the card perks like this:The British Airways Card has the best perks. It offers 10% off all paid flights, and up to $600 award rebates. The Iberia Card also offers the best perks. The reward for spending $30,000 (a $1,000 Iberia discount coupon) is very valuable. The Aer Lingus Card provides the least perks.These bonuses can help you earn a lot of AviosWhen deciding which card to apply for, keep in mind that you could be eligible for any of the cards. I have the British Airways Card and I intend to get the Aer Lingus Card and Iberia Card. This could be another factor that will decide between these cards.Which Avios credit product do you most value?
