Hey awardtrail readers! November's here, and the airline shopping portals are bringing the heat with a chance to snag a combined 18,500 bonus points and miles! Basically, airline shopping portals (think online malls where you earn miles for your purchases) are offering up to 5,000 bonus miles *each*. The great thing is, all five major airline portals – American, United, Delta, Southwest, and Alaska – are participating. And unlike some flash sales, you've got a decent amount of time, up to 24 days, to hit the spending requirements and maximize your earnings. Why does this matter to you? Well, if you're already planning on doing some holiday shopping online, why not earn a ton of extra miles for it? These bonus miles can seriously boost your award balances and get you closer to that dream vacation, all for purchases you were going to make anyway. Time to shop smart!
