Can you smoke IQOS on a plane?

Electronic cigarettes that produce smoke without the use of a flame (e.g. iQOS) are allowed in carry-on baggage, but not in checked baggage. Furthermore, the use of electronic cigarettes while on board is prohibited due to the fact that it could make other passengers feel uncomfortable or cause misunderstanding.



No, you cannot use IQOS or any other heated tobacco or electronic smoking device on a plane in 2026. While IQOS is a "heat-not-burn" product rather than a traditional cigarette or vape, global aviation authorities (including the FAA, EASA, and ICAO) treat all such devices under the same strict "no smoking" category. Using them on board—including in the lavatories—is a federal offense and can trigger smoke alarms, leading to heavy fines or arrest. Furthermore, because IQOS devices contain lithium-ion batteries, they must be carried in your carry-on luggage and are strictly prohibited in checked baggage due to fire safety risks. You must keep the device powered off for the duration of the flight and wait until you reach a designated smoking area outside the terminal after landing to use it legally.
