Mileage shopping portals are a great way of getting bonus miles for purchases that you’re going to make anyways. Rather than going directly to the store’s website, just a few more clicks through a shopping portal can earn you hundreds — if not thousands — of additional points. In fact, shopping through a portal is so useful that it earns the #6 spot on our Essential Travel Tips for beginners.And, today, we have some good news for travelers seeking Avios: Now through May 31, British Airways’ shopping portal is awarding 3x the standard earning rate.Some of the notable offers are:eBags: 24x (36-cent return per $1 spent, based on current TPG valuations)Sunglass Hut: 24xOverstock.com: 21x (31.5 cents per $1 spent, based on current TPG valuations)Neiman Marcus: 18x (27 cents per $1 spent, based on current TPG valuations)Pottery Barn: 18xWest Elm: 18xBed, Bath, and Beyond: 12x (18 cents per $1 spent, based on current TPG valuations)Sam’s Club: 12xWalmart: 12xMacy’s: 9x (13.5 cents per $1 spent, based on current TPG valuations)Apple: 6x (9 cents per $1 spent, based on current TPG valuations)Target: 6xIf you’re not sure how to get (at least) 1.5 cents per Avios in value, we just did a deep dive into British Airways’ distance-based award chart.My favorite Avios redemption so far was transferring 25,500 BA Avios to Iberia Avios at 1:1 and booking Iberia’s excellent premium economy product from New York’s JFK to Madrid (MAD) — netting me a 12+ cent per Avios value on the last-second booking on the inaugural flight.It’s wild to think that you need to spend just $1,063 at either eBags or Sunglass Hut to earn enough Avios for a one-way premium economy flight to Europe!Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
