Packing potato chips for a flight requires a strategy to prevent them from being crushed by shifting luggage or popping due to cabin pressure changes. If you are packing them in carry-on luggage, the best method is to keep the bag at the very top of your backpack or tote, ensuring nothing heavy is placed on it. For checked luggage, you should place the chip bag inside a sturdy, airtight plastic container (like Tupperware) or a rigid cardboard box to create a "crush-proof" barrier. Interestingly, because airplane cabins are pressurized to a higher altitude than sea level, the air trapped inside a sealed chip bag will expand during flight; while bags rarely "explode," they can become very tight and prone to leaking. To mitigate this, some travelers use a small pin to create a tiny "pressure-relief" hole in the bag and then seal it with tape, though using a rigid container is generally more effective. Alternatively, purchasing "Pringles" or other canned chips provides a built-in protective shell. Regardless of the method, always ensure the chips are in your "personal item" if you want to snack during the flight without digging through an overhead bin.
