Spring! It means a couple of things to me that might at first seem opposites: spring cleaning and spring travel. Here’s how they’re related: A thorough wallet cleaning — by which I mean retiring old credit cards and getting in on new offers — can pave the way for more travel and more rewards for adventures this season and beyond. If you travel for business, so much the better!

A couple of the very best travel rewards cards are on offer right now for a limited time:
