In preparation for a 2013 nobo thru attempt, I have been trying to determine the best way to check you backpack when flying. I have thought about putting my pack in a duffle bag or suite case (used and cheep from a garage sale or goodwill). My question is, what I would do with the suite case once I got to Atlanta. With all the security at the airport I am uncomfortable with the idea of trying to throw away a bag at the airport.
