Rules for the transportation of portable electronic devices
The transportation of portable electronic devices (including electronic cigarettes, pipes, other personal vaporizers, as well as power banks and spare batteries) containing lithium batteries is only permitted in carry-on luggage; the transportation of portable electronic devices in checked luggage is prohibited.
Spare batteries and power banks must be protected against short circuits by being placed in individual retail packaging or by insulating the terminals (it is necessary to insulate the terminals and/or place them in a separate plastic bag or protective case).
The above-mentioned restrictions also apply to transfer passengers connecting to flights of other airlines at the transfer airport. Please check for any transportation restrictions on the official website of the airline operating the connecting flight.
