Don't spoil your trip or risk the safety of others by shipping fireworks through cargo or as passenger luggage. Your airline, travel agent, and the FAA remind you that fireworks can be a great danger in the air. Don't take them with you on the plane.
Fireworks are a real danger to all aboard a plane. They can start a fire just by rubbing against something else. Sending fireworks by air falsely marked as clothes, tools, books, or foodstuff is against the law and very dangerous. You can get up to five years in prison and/or a big fine for taking fireworks onto a plane or trying to ship them illegally by air.
