Verdict - In most of my reviews, I'll normally do some peer comparisons with other cards just to see how it really stacks up. In this case, there is really no need for that. Why? Because this is one of the truly rare airline credit cards that has no annual fee and yet allows you to earn double miles. In the past, airline cards allowed you to waive the annual fee, but it came at the price of only allowing you to earn one miles for every two dollars that you spend in the card. So this card is really an exception.
The only gripe one can have about this card is that there is no mega sign up bonuses. But when you only need 45,000 miles to fly to Ireland, can you really complain? At the end of the day, this card will appeal most likely to Irish immigrants to fly home once every couple of years because it is the only card that let's you earn Aer Lingus miles. They do not have partnerships with other cards like Membership Rewards or Starwood. Hence if you want to earn Aer Lingus miles, this is the only card to get. But with no annual fee and the ability to earn doubles, this would be a no-brainer.
