This question already has an answer here:

As we know, according to IATA passengers allowed to carry no more than 100 ml of liquids on board. Yet when traveling with low-cost airlines, you are not offered any water on board. This is quite harmful, considering the dry air in the cabin. Being used to my country laws and social norms that allow anybody to ask for a free glass of water in any place that serves food, it sounds strange that I don't seem have the official right to ask for a glass of drinking water during the flight. Are there any IATA regulations or subject, or is it based purely on airline good will decision?

    Have you tried asking the flight attendants? "Not offering" isn't the same as "not available upon request". – Snow Dec 7 '17 at 7:06

    "passengers allowed to carry no more than 100 ml of liquids on board" Where does it say this? If you're referring to the limits at the security check, nobody hinders you from bringing an empty bottle through security and filling it up with water after security. In fact, e.g. at US airports you find very often water taps to exactly do that. Otherwise just buy a bottle of water in one of the many shops in the secure area. – dunni Dec 7 '17 at 7:22

    You can always book regular carriers, where food and drink is included in the price. With low cost carriers, you have the advantage of low prices with the disadvantage of low service. – dunni Dec 7 '17 at 7:47

    The IATA best practices guide has only rules about serving alcohol (iata.org/publications/Documents/…). If you're asking about a country specific law, you should specify the country, otherwise it would be too broad. But i can tell you that at least for germany, there is no such law. – dunni Dec 7 '17 at 7:54

The IATA best practices guide (http://www.iata.org/publications/Documents/cabin-operations-safety-bp-guide-2015.pdf) has only rules about serving alcohol to passengers. So it is safe to assume, that there is no other IATA rule regarding drink service. When it comes to laws, each law would be country specific. At least Germany doesn't have such a law, which would require airlines to provide free water.
