As we know smoking in Dubai is allowed but has some limitations. And vaping is also allowed in places where you can smoke. Vapers and e-cigarettes are in most cases allowed onboard in the flight. Emirates, for example, allows passengers to bring electronic cigarettes on board. A vaper may only be transported as hand luggage and not as checked baggage. Additionally, you must switch off the electronic cigarette and wrap each battery separately in a secure pouch. Liquids and e-liquids are not permitted in carry-on luggage. These, like other liquids, are only allowed in checked baggage.
