Emirates has added new functionality for its U.S.-based members. The airline is offering U.S. members of its loyalty program the opportunity to earn miles through shopping online through a portal. Members of the Skywards program can now earn Skywards Miles at 1,500 U.S. and U.K. brands.Online shopping portals are arguably one of the easiest and best ways to earn miles. All it takes is an extra couple of clicks to open up your preferred airline’s shopping portal of choice where you’ll then be directed to the website of the retailer of your choice. The simple process means you get rewarded for purchases you were going to make anyway, sometimes up to as many as 40 miles per dollar spent.Skywards members can access Emirates’ shopping portal either through the Emirates app or through the dedicated website.We had a look at the number of Skywards miles being offered per $1 spent. Here are a couple of popular examples as of time of writing.AppleEmirates: 1.5 miles per dollar spentAsosEmirates: 3 miles per dollar spentEbagsEmirates: 4.5 miles per dollar spentRay-BanEmirates: 3 miles per dollar spentAll of these promotional rates expire on Aug. 31, 2020 except for Apple, which expires on Aug. 12.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
