Yes, vapes like RELX can be taken on a plane.
However, we recommend you take the RELX Vapes with you but not put them in checked luggage. Because it would get you accused of transporting lithium batteries privately in checked luggage.
Furthermore, vaping on the plane would also be against the rules of some airline company.
In addition, taking RELX vape on the plane would also cause e-liquid leakage due to high air pressure.
