Passengers boarding flights at Russian airports will be allowed to take more than the previously allowed 100 milliliters of water with them beginning in September, a news report said Wednesday.
Plans to relax the regulation were originally announced by authorities in April, together with rule changes allowing many travelers to leave their belts and shoes on at airport security checkpoints.
The hassle-saving measure comes as a result of domestic airport authorities' decision to install equipment capable of determining liquids' makeup from a distance, Rossiiskaya Gazeta reported.
At present, the rule change will only affect water and will not apply to liquids in metal containers, the newspaper clarified.
Passengers will still have to stow flammable and high-alcohol-content liquids in their checked baggage.
Airport officials have restricted carrying liquids on board planes except in small volumes after British special service operatives prevented a series of terror attacks using so-called "liquid bombs" in August 2006, according to news portal Lenta.ru.
Only baby food and liquid medicine were exempt from the regulations, which were introduced all over the world.
