I know liquids over 4oz are not allowed. I was wondering about food. I am bringing 7 days of dehyrated food and other snack items (non-liquid) on board. Will this go through the gate? Or is it, the only food allowed on the plane is that which is purchased after the gate? I'm sending the Hiker Hostel a box with my treking poles and some other items. I could just put the food in there but I was looking to cut down on the shipping weight. Thanks
