Puff bars are classified as disposable electronic cigarettes, which Transportation Security Administration states are under no circumstances allowed in your checked luggage but are allowed in your carry-on luggage. Therefore, you can bring a puff bar on a plane, just as long as you store it in your carry-on luggage.

Yes, in 2026, Puff Bars and all other electronic cigarettes or disposable vapes must be carried in your hand luggage (carry-on). They are strictly prohibited from being placed in checked baggage due to the fire risk associated with their internal lithium-ion batteries. If a battery malfunctions or "thermal runways" in the pressurized cargo hold, it can be catastrophic, whereas a fire in the cabin can be managed by the crew using specialized fire containment bags. When passing through security, you should treat your Puff Bars like other electronics; some airports may require you to place them in a separate bin. Additionally, any "pre-filled" vape device is subject to the 3-1-1 liquids rule if the airport security considers the e-liquid content significant, though most disposable Puff Bars are small enough to be ignored. It is vital to remember that while you can carry them on board, vaping is strictly illegal on all commercial aircraft and in most airport terminals worldwide. Using a Puff Bar in an airplane lavatory will trigger sensitive smoke detectors and can lead to heavy fines, an emergency landing, or even arrest upon arrival.
