When you travel do you register for "loyalty points", frequent flyer miles, etc.? If not, you should. They can add up to some decent hotel or rental car savings, upgrades, and even free nights' stays. Frequent flyer miles add up, sometimes quickly, to free tickets.
Now that you're registered, how do you keep track of them? Recently I came across a website that may be useful when managing those points. It doesn't have all the airlines, hotels and car rentals yet but they seem to be working on that. You can even share, trade, or buy points. It's worth looking at and it's free to join.
Check out www.points.com. It may work for you.
