Good news! After disappearing a few months ago, Giftcards.com has returned to airline shopping portals. In addition to making it easier to earn miles/points through the portals, it also makes it easier to earn the bonus miles/points when there are promotions such as ‘Spend $150 and earn 500 bonus miles’.
In addition to the Cartera-run airline portals (United, American Airlines, Alaska, United and Delta), it’s also available on other travel portals including Wyndham, Virgin, JetBlue and Emirates.
