Unopened bottles will not be allowed through unless they are 3.4 oz or less.
ALL liquid, paste, gel, cream, ANYTHING of like consistancy MUST be in 3.4 oz containers and then those containers MUST fit inside a quart-size zip top bag. AND IT MUST CLOSE. (Not a sandwhich bag, and not the larger gallon, the size in-between.) One zip top bag per passenger. Then, once you approach the x-ray, you must remove the zip top bag from your carry-on and place it into a bin with nothing below or on top of it.
There are no restrictions on liquids in checked baggage except in the case of the liquid being a hazardous material, such as gasoline, which would not be permitted.
