I used to travel quite a bit in my last job and accrued some random airline miles here and there. I couldn’t keep track of how much I had and where they were until I found out about Awardwallet.com. It’s a free site that tracks your balances in one convenient place and even alerts you if your miles are going to expire. Although you might want to manually check once in a while, because I had some Jetblue credit expire on me. You can get a free six month upgrade for first-time users if you use the following coupon code: free-yfakbw.
