As of 2023, the regulations regarding vaping on planes can vary by country and airline. However, in general, it is not recommended to bring a vape device or e-cigarette on a plane due to safety concerns.

In the United States, the Federal Aviation Administration (FAA) prohibits the use of e-cigarettes or vaping devices on commercial flights. This includes the use of the device during the flight, as well as charging the device in-flight or packing it in checked luggage. The FAA cites safety concerns related to the potential for the device’s lithium-ion batteries to overheat or catch fire, as well as the potential for secondhand exposure to the aerosol produced by the device.
In addition to the FAA’s regulations, many airlines also have their own policies regarding the use and transportation of vaping devices. For example, some airlines prohibit the use of e-cigarettes or vaping devices on all flights, while others may allow them in certain designated areas on the plane. It is important to check with your airline prior to flying to ensure that you are aware of their specific policies regarding vaping devices.
If you are planning to bring a vape device or e-cigarette with you on a plane, it is recommended to pack it in your carry-on luggage rather than your checked luggage. This is because the potential risk of a lithium-ion battery catching fire or exploding is greater in the cargo hold than in the cabin. Additionally, it is important to ensure that the device is turned off and that the battery is disconnected to prevent any accidental activation or charging during the flight.
It is also important to note that some countries may have stricter regulations regarding vaping devices than others. For example, in some countries, the possession or use of vaping devices may be illegal, and travelers may face legal consequences for bringing these devices into the country. It is important to research the regulations and laws of your destination country prior to traveling with a vaping device.
In conclusion, as of 2023, the regulations regarding vaping on planes can vary by country and airline. However, in general, it is not recommended to bring a vape device or e-cigarette on a plane due to safety concerns related to the potential for lithium-ion batteries to overheat or catch fire, as well as the potential for secondhand exposure to the aerosol produced by the device. It is important to check with your airline prior to flying to ensure that you are aware of their specific policies regarding vaping devices, and to pack the device in your carry-on luggage rather than your checked luggage to reduce the risk of fire or explosion. Additionally, travelers should research the regulations and laws of their destination country prior to traveling with a vaping device to avoid legal consequences.
