I had mentioned the cost of luggage check-in at the airlines. I found this chart by Hipmunk, a flight search engine that seems to be appearing everywhere all of a sudden. The reason is apparent once you try it. The searches are incredibly visual aiding excellent decision making. They now have apps for smart phones too. Clicking on the picture will make it larger. I wish that worked with other things. ; ) If you want it even BIGGER, go here.
