Here are my 2 cts:
a) If you are as fat as most of the TSA guys your clean Levi's will be gone. If you are of average European weight you might have a chance. If you are skinny the bag handlers at JFK will like them.
b) Samsonite is something the TSA morons especially like to break into with their crowbars. They avoid cheap luggage as this is only half the fun.
c) You can easily put perfumes into the Samsonite, this is something the TSA folks do not use ( although it would be a great idea for some of them ).
