No matter the destination, knowing how to pack bags properly can avoid added stress to the travel experience. While many may believe that items allowed in checked bags are a “free for all,” the reality is nothing but. Out of the safety of passengers, crew, and aircraft, regulators such as the Transportation Safety Administration (TSA) have lists of what is approved and prohibited in checked baggage. Although the criteria may be less restrictive than what is permitted in carry-on bags, some everyday items are not allowed to fly or are subject to special instructions when packing them.
