Heads up, Amex Business Platinum cardholders! There's a targeted upgrade offer floating around that could land you a pile of Membership Rewards points. Specifically, Amex is dangling 50,000 Membership Rewards points if you upgrade your Business Gold or Green card to the Business Platinum and spend $10,000 within the first 3 months. There have been offers as high as 140,000 points in the past, so keep that in mind. You can find upgrade links online, but these offers are often targeted, so YMMV ("your mileage may vary," meaning it depends on your individual circumstances). Here's why this matters to you: If you've held the Business Platinum before and missed out on the welcome bonus, this upgrade could be your second chance. The card does come with a hefty $895 annual fee, so you need to weigh the benefits against that cost. You do get a $200 airline incidental credit, solid lounge access (Centurion, Delta SkyClub, Priority Pass), and other perks like hotel elite status. However, consider whether you'll actually *use* those perks. The big question is, is it worth it? If you can easily hit the $10,000 spending requirement and will take advantage of the Platinum's perks, it could be a good deal. Especially if you've been wanting to get those points! But if you already have another Platinum card or won't use the benefits, the annual fee might not justify the bonus. Do the math and see if this upgrade aligns with your travel and spending habits.
