If you who want to try out the upgraded version of Award Wallet, a discount code is posted in this Flyertalk thread. I’m not listing the code because I believe if you use it, you should post a thank you to the person who posted it in the thread. It appears that only one person has used it as of the time of this post and there are 10 available.
Award Wallet is a web site that helps you keep track of all of your loyalty program points/miles. The free version will keep track of when miles are expiring for 3 accounts (it will tell you the balance of any others; just not when those miles are expiring). It also keeps track of upcoming itineraries on those accounts.
I do use Award Wallet. It makes tracking your miles much easier.
