Heads up, United credit cardholders! United is running a targeted promotion called "Say Yes to More Travel in 2026" that could net you up to 15,000 bonus miles. The catch? You need to be specifically targeted for the offer and then hit a spending requirement between January 1 and March 31, 2026. So, why should you care? Free miles, of course! These miles can be used towards award flights, upgrades, or even merchandise. If you're targeted and already planning on doing some spending during that period, it's basically free miles for doing what you were going to do anyway. To see if you're eligible, keep an eye on your email or your United account for the offer. If you see it, be sure to activate it! The specific spending requirement to earn the 15,000 miles will vary from person to person, so check your offer carefully. Don't miss out on this potentially easy way to boost your MileagePlus balance!
