There should be a list printed on your ticket. Liquids, flammable material including some batteries, snakes 🐍 and other charming critters, guns, ammo, knives, glass bottles, and more. Weight sets are also not allowed. So are folding ladders and other bulky items. Do check the website. Happy flying.
