United MileagePlus members, listen up! You can now snag some easy miles just by linking your United account to your Instacart account. The basic deal is this: link 'em up and then complete just one Instacart order within 60 days, and boom, you'll get 500 bonus miles. This offer is valid all the way until October 5th, 2028, so you have plenty of time to take advantage. But wait, there's more! If you're new to Instacart, the deal gets even sweeter. New users can rake in a whopping 5,000 United miles after placing four Instacart orders within your first eight weeks. Plus, keep an eye out for an offer to get $0 delivery fees surrounding your United domestic flights. That means no delivery fees for a week before and two weeks after your flight. This offer is valid until September 28, 2028. Why should you care? Free miles are always a good thing, especially when they're this easy to get. If you already use Instacart, linking your account is a no-brainer for a quick 500 miles. If you've been on the fence about trying it, the 5,000-mile bonus for new users might be just the push you need. Think of it as getting rewarded for doing something you already do – buying groceries! Those miles can add up quickly and get you closer to your next award flight.
