So, you just snagged a sweet new Citi card with a juicy sign-up bonus, right? Awesome! But here's the thing, one of the most common mistakes award travelers make is accidentally missing out on that bonus. It's easy to do! You might miscalculate how much you need to spend, forget the deadline, or mistakenly think that annual fee counts towards your spending. Thankfully, Citi's got a handy tool to prevent this from happening. They offer a sign-up bonus tracker right in your online account and in the mobile app. It lets you easily see how much you've spent and how much time you have left. This is a total game-changer because it takes the guesswork out of the equation and ensures you actually get those hard-earned bonus points or miles! No more spreadsheets or frantic calculations – just easy, at-a-glance tracking. Definitely worth checking out if you're chasing a Citi bonus!
