All Iberia flights are non-smoking. The use of cigarettes, cigars, pipes, e-cigarettes and any similar devices is prohibited on all our planes.

The International Civil Aviation Organisation (ICAO) has banned the carriage of electronic cigarettes in checked baggage in the hold, but you are allowed to carry them in the cabin, provided they are kept in their case or protective bag (although you can't use or recharge them).
When you board the aircraft, place them in your pockets, in the seat pocket in front of you, or under the seat in front of you. It is strictly forbidden to place them in the overhead lockers.

Regulations regarding e-cigarettes vary by country. Check the official government website of each country you are travelling to or departing from to confirm the current restrictions and requirements.
