See privacy policy.For Monday only, score an elevated bonus on Apple purchases made through the American Airlines AAdvantage shopping portal. The one-day offer will earn you 6 miles per dollar spent on select Apple purchases as opposed to the standard offer of 1 mile per dollar.In order to be eligible for the one-day elevated offer, you must make your eligible Apple purchases through the AAdvantage shopping portal. According to the terms and conditions, the iPhone X, Apple Watch Series 3 and TV 4K are not eligible for the offer. In addition, the terms state that some newly released products may not be eligible. Other products that aren’t eligible include gift cards, gift wrap, Bose products and expedited shipping.For a retailer that doesn’t often offer bonuses, this is a really nice elevated offer. For example, if you buy an iPhone 8 Plus for $949 and a set of AirPods for $159, you’d walk away with 6,648 American Airlines miles. Based on TPG’s most recent valuations, those bonus miles are worth $93.Shopping portals are one of the best ways to earn bonus miles with an airline to put you on your way to your next award. If you know you’ll be making an online purchase — especially an Apple purchase — be sure to do it through a shopping portal in order to earn the bonus miles.
