It seems that the rules for flying are always changing. To best know which things not allowed on airplanes today, it helps to consult the TSA. The TSA (Transportation Security Administration) posts a helpful chart on their website pertaining to the question, what can I bring on a airplane. The site details category by category and item by item what can and not be brought on via carry-on or
. checked luggage. They cover in specifics such categories as sharp objects, sporting goods, guns and firearms, tools, martial arts and self-defense items, explosive and flammable materials, disabling chemicals and other dangerous items. Categories are further broken down by item and method of transport (carry on vs. checked). Please keep in mind that some items are strictly prohibited while others are simply prohibited from being packed in your carry-on luggage.
