I probably didn't state my inquiry too eloquently. My question is not while you are on the trail but for the flight where you are planning on stashing those belongings? In your backpack or somewhere else? Also remember that unless you have status, if your checked bag weighs over 50 lbs., the fee dramatically increases, which is one of the reasons I have insisted that each scout's checked bag weigh under 50 lbs. and one way to minimize weight is to go with a duffel without wheels.
