TRANSPORTATION OF MEDICINES AND DIETARY SUPPLEMENTS IN HAND LUGGAGE

The transportation of medicines and dietary supplements in hand luggage is agreed in advance by the passenger with a representative of the airline - carrier (operator).
In advance of departure, a passenger who is sick and needs to take medication (or receive injections) during the flight must notify the representative of the airline - carrier (operator) and receive information about the mandatory availability of relevant medical documents.
It is allowed to carry medicines (including syringes or other injection devices) in hand luggage that the passenger cannot do without during the flight for medical reasons: insulin, antihistamines, painkillers, etc. The need for taking and the amount of medicines is determined by the doctor, based on the duration of the flight and is indicated in the relevant medical certificate with the doctor's personal wet seal.
During the aviation security check, passengers carrying medication in their hand luggage (including syringes or other injection devices) must notify the aviation security officer at the security checkpoint and provide a medical certificate, who will call an airline representative to coordinate the transportation of the specified items. After the airline representative confirms the possibility of transporting medication in hand luggage and the passenger passes the aviation security check procedure, he is allowed to board the flight.
Depending on the physical condition of the passenger (availability of relevant documents, certificates, etc.), the representative of the airline - the carrier (operator) has the right to refuse the passenger transportation or allow his transportation

Portable medical electronic devices

With the permission of the airline portable medical electronic devices (automatic external defibrillators, inhalers, devices that maintain continuous positive airway pressure, etc.) containing lithium metal or lithium-ion cells or batteries may be carried by passengers for medical purposes. 
External battery (PowerBank) An external battery is a highly specialized accessory: a small-sized charger that stores accumulated energy for a long time.
Airline permission is not required for the carriage of lithium metal batteries with a lithium content of less than 2 g or lithium-ion cells or batteries with a specific power of less than 100 Wh.
A passenger is allowed to carry no more than two spare batteries with a lithium content of more than 2 g, in the case of lithium metal batteries, and with a specific power in watt-hours equal to 100 Wh, in the case of lithium-ion batteries. Spare batteries must be individually protected in a way that prevents short circuits (for example, by placing them in retail packaging, or by taping the exposed terminals, or by placing each battery in a separate plastic bag or protective package), and carried only in hand luggage. Each installed or spare battery must be of the type that meets the requirements of Subsection 38.3 Part III of the UN Manual of Tests and Criteria. 
Lithium-metal batteries with a lithium content exceeding 8g or lithium-ion batteries with a specific capacity exceeding 160 Wh are not permitted for carriage (neither as spare batteries nor in devices).
Portable, battery-operated electronic smoking devices
(e.g. electronic cigarettes, electronic vapes, electronic cigars, electronic pipes, personal vaporizers, electronic nicotine delivery systems) may be carried by passengers or crew members in the cabin for personal use only. 
Spare batteries must be separately protected to avoid short circuits and must be carried in hand luggage only. The lithium content of the batteries must not exceed 2 g and the specific capacity of lithium-ion batteries must not exceed 100 Wh. The type of batteries and cells must meet the requirements of each test given in the UN Manual of Tests and Criteria, Part III, Subsection Charging devices and/or batteries on board the aircraft is prohibited. 
Portable electronic devices (including medical devices) for personal use containing lithium metal or lithium-ion cells or batteries.
Portable electronic devices (watches, calculators, cameras, mobile phones, laptop computers, camcorders, etc.) containing lithium or lithium-ion cells or batteries must be carried as hand luggage. If the device is transported as checked baggage, measures must be taken to prevent its unauthorized activation.
Spare batteries must be separately protected to prevent short circuits and must be carried only in hand luggage. Batteries and cells must be of a type that meets the requirements for passing each test set out in the UN Manual of Tests and Criteria, Part III, subsection 38.3. For transportation of portable electronic devices containing lithium-ion batteries and spare lithium-ion batteries with a watt-hour rating of 100 Wh but not exceeding 160 Wh require airline approval. No more than two individually protected spare batteries per person. 
Small medical or clinical mercury thermometer
One small medical or clinical thermometer containing mercury for personal use, only in checked baggage, if it is in a protective case.
Hair curling
