Shopping portals are one of the best ways to earn points and miles with your favorite airline — without even having to step on a plane. Just by making a purchase online with select retailers through a portal, you can earn valuable points and miles, which can then be used toward your next redemption. Now, with holiday shopping season upon us, shopping portals are more valuable than ever — especially with Black Friday promotions and elevated offers.Because shopping portals are always updating, it’s beneficial to see what each of the major US carriers offers at any given time — and all in one place. So, we’re rounding up some highlights of elevated offers each week, as well as any promotions you should look out for that could earn you even more.Disclaimer: This is a selection of retailers currently offering elevated offers, not an exhaustive list of all offers. In addition, there’s no guarantee that any or all of these offers will be around longer than one week. If you’re considering making a purchase from a retailer based on its offer with a particular airline, it’s better to do that sooner rather than later before it’s gone.Alaska AirlinesRetailer Elevated Earning (Miles per Dollar) Regular Earning (Miles per Dollar) Amount of IncreaseAnthropologie21+1Athleta41+3Aveda43+1Banana Republic31+2Barnes & Noble32+1Barneys New York (through 12/30/17)62+4Bloomingdale’s (through 11/22/17)60.5+5.5Blue Apron (through 12/31/17)5501,100+550Clinique43+1Coach41+3DKNY31+2Finish Line (through 11/30/17)62+4Free People21+1FTD.com117+4gap.com31+2HP.com51+4Hugo Boss32+1Kohl’s (through 11/24/17)42+2Lowe’s10.5+0.5Macys.com (through 11/21/17)62+4Neiman Marcus (through 11/27/17)62+4Neiman Marcus Last Call32+1New Balance54+1Nike41+3Old Navy31+2Origins431Perry Ellis43+1RalphLauren.com42+2Rebecca Minkoff43+1Sephora.com42+2Staples.com32+1Timberland42+2Toys ‘R’ Us10.5+0.5Walgreens32+1Wine.com42+2Other OffersAlaska has a tab on its Mileage Plan shopping portal dedicated to Black Friday offers.

Don’t navigate away from the page and complete your purchase in another window — you may miss out on the bonus points or miles.Make sure cookies are enabled on your browser for the retailer’s site. The portal will then be able to “track” your purchases and award you the miles or points that are owed.Only use promotions or promo codes found on the portal. If you use others, it may disqualify you from earning any bonus points or miles.Read the small print. When you’re making a purchase or trying to take advantage of a promotion or elevated offer, be sure to read the restrictions to see if any specific items aren’t eligible for bonus points or miles.
