I have a drawer full of AK's at home (probably over 100). Once I realized I had a problem, I started leaving them on the plane in a strategic location in the hopes that the waifs and strays from economy will scoop one as they shuffle up the aisle....
The only one I really really use daily are the blue AA amenity bags from the 90's. They are perfect for a pair of shoes or to keep my kippie bag in (yes, it's leaked something often enough that a bagging is in order...)..
