Earn hundreds (possibly thousands) of bonus miles with these airline shopping portal promotions

Editor’s note: This is a recurring post, regularly updated with new information and offers.

Maybe you’re planning a major vacation, or you simply want to top off your airline account with some extra rewards. Did you know you can use an online shopping portal to earn cash back or additional airline points or miles for each dollar you spend? Seriously, earning these rewards may be one of the best kept secrets in the world of points and miles — and we are here to clue you in.

Right now, several airline shopping portals are offering holiday bonuses that give you a chunk of miles when you spend a certain amount. This is in addition to the per-dollar rewards you would normally receive when using these portals (for example, 3 miles per dollar spent at a given store). You generally don’t have to spend the minimum amount at once; you can reach it by making multiple smaller shopping trips over the course of the promotion. With one of these bonuses, you can get a much higher return on your spending than you normally would through the portal.

Bottom line

If you plan on doing some online shopping for yourself or for Mother’s Day, you might as well be rewarded for it. Aside from purchasing gifts or one-off items online, this is also a great chance to stock up on things you’d normally buy anyway.

For example, the United Airlines portal is currently offering up to 2 miles per dollar spent on purchases at Walmart. If you spend $100 (which isn’t hard to do when stocking up on household items and groceries), you’ll receive a total of 700 miles in your United MileagePlus account — 200 miles for the purchase, plus 500 bonus miles. If you frequently fly United, this is a great way to boost the miles in your account, which you can redeem for your upcoming travel plans.

If you’re like us and can’t pass up a good rewards deal, then happy shopping.
