I was on AirNav.com tonight looking at some airports and saw that they've added their "AirBoss" members-only fuel discount program. You have to be a member to see what the discount is, but they say it's between $.05 and $2.10 per gallon, averaging $.20/gal. That's quite a range. It's $40/yr for membership.
Anyone use this, and what have you found?
