 Months out to a couple of days ahead of time. So some really cool tools from Google that I love. And then credit cards, oh my gosh. Get a good credit card that has a big sign-up bonus. But if you're just starting out in that, get one that has a transferable currency where you get a big sign-up bonus, and then you can transfer those points into different airlines or hotels. I like the Chase cards, and then I transfer them to Hyatt Hotels for some amazing redemptions. But there's all kinds of good stuff out there.
