Why you can not carry liquids into the plane, whether this rule is acting everywhere and what restrictions can be in the stores Duty Free?
Before passing into the "clean zone" of the airport, border guards are asked to lay out the favorite perfume and mineral water at all from harmfulness, but for security purposes. Restriction on the implementation of fluid in hand baggage was introduced in 2006, after a series of terrorist attacks series. Then in London was detained a citizen of Great Britain Abdulla Ahmed Ali, who had a connection with Islamic radicals and in his baggage substances that could undermine several aircraft. They were disguised as orange juice.
After that, a number of countries introduced a restriction on liquids in hand baggage. Among the first amendments, the USA and the EU countries, as well as Switzerland, Russia, Iceland, Croatia, Israel, Egypt, Morocco, Tanzania and Norway. Today this rule works in almost all countries of the world. The fluids are regulated by internal laws, there is no uniform international document. In Russia, this order of the Ministry of Transport of the our Federation "General rules for air transportation of passengers, baggage, cargoes and requirements for passenger services, shippers, consignees" .
At the moment, most countries have adopted the security policy, operating in the United States (with their standards can be found on the official website of the Department of Internal Security) and the EU: the passenger can carry into the "pure zone" of departure to 1 l of liquid. At the same time, each container should be no more than 100 ml. And if you have a 200 ml container with you, filled with half or even less, take it into manual sting anyway. And the concept of "liquid" also includes sprays, jelly-like and pasty substances. Such seemingly far from water objects like caviar, jam, toothpaste, or mascara, fall under the limit and can be removed when exceeding the allowable volume.
In some countries, passengers need to put all fluids into a hermetic transparent package (at the moment this rule is valid in the USA, Great Britain, Canada, Australia, Japan, Hong Kong, China, New Zealand and several more countries). But even if you fly to the country to which this requirement does not apply, it is better to pack liquids in a separate transparent package, so that you can show them on inspection, without getting all things. With internal flights, restrictions on liquids may be absent, as happens in Australia. But it is rather an exception than the rule. In developing countries, the fluid fluid is often completely prohibited. Therefore, before the flight it is better to contact the airline and clarify the details.
However, even where restrictions on transportation in manual layer are applied, the rule has its exceptions.
First, in hand bags it is allowed to carry liquid drugs in factory packaging, if you require medical testimony. But there are nuances. In some countries, a ban on the drugs permitted in Russia. Therefore, before the flight, it is necessary to explore the legislation of the country where you are heading, and get a doctor from a doctor in English, proving that this medicine is vital to you. Otherwise, vacation can end and not started. If the customs it turns out that there is no recipe, and you have a criminal case forbidden to import, a criminal case can be arranged for you.
Secondly, baby food can also be taken. But it should be in factory unborn packaging and only in the quantity that the child will need for the flight. Even better if it is a dry mixture, since children’s puree and cereals also belong to liquids. All food is better to transport in a separate bag, which shows that its content is intended for your small satellite. Typically, such hand balees are loyal, but sometimes on inspection asked to open a jar with food to make sure of its safety.

Limit in volume does not apply to fluids purchased in duty-free shops. Therefore, on board you can safely carry a bottle of water, alcohol or, for example, a bottle of perfume. Since the goods in the stores Duty Free are a special test, including the content of flammable and explosives, they are considered safe. But to open them during the flight is still prohibited. If the packaging integrity is violated, the goods fall under the norms about transporting hand-made bags and it has the right to withdraw.
However, Duty Free may also restrict. Some countries that are part of the European Union, left the veto on the import of goods purchased in the free trade zone outside the EU. For example, if the passenger in front of the flight from Moscow to Paris buys in the Duty Free perfume, and the content of alcohol in them exceeds the norms established by the EU legislation, or their name is made to the France’s Customs Stop list, they can withdraw them (if only during Flight You do not spend the bottle).
The complexity is that each country has its own stops. Moreover, with transit flights, goods from Duty Free may be asked to shift in baggage (in accordance with the rules of the airline). Usually, the lists of prohibited items are regulated by local analogues of the Customs Code of the our Federation. Most often prohibited or limited importation of alcohol and alcohol-containing goods, such as perfumes, medicines and even some cosmetic lotions.
List of goods allowed to import goods or their total cost can be found from the air carrier, and it is desirable to do it in advance. But if you decide to buy a bottle of perfume Suddenly, you can already call the airport to the airline or try to contact its representatives at information racks.
