The reason for all the effort is that some Pacific and Asian cultures traditionally celebrate a new year with pyrotechnics. FAA's security inspectors in Hawaii got the effort moving in anticipation of a higher than normal number of passengers trying to take fireworks aboard aircraft in the Pacific this holiday season. In both brochure and web site the message is simple. Fireworks are a real danger to all aboard an airplane and passengers should not carry them in their luggage. Not in checked baggage and not along with them in the cabin.
Fireworks can start a fire just by rubbing against something else.
Sending fireworks by air falsely marked as clothes, tools, books or cookies is against the law and very dangerous. That's because the airline workers can't know how to safely handle them. Federal rules forbid transporting fireworks in passenger carry-on or checked baggage. Many airlines have special rules for fireworks as cargo that may be more restrictive than federal guidelines and some airlines may ban them outright. To ship fireworks, passengers should coordinate with their air carrier to ensure they are safely and properly packed, labeled and declared.
