Is this new? Why wouldn't they say in the article that flasks must fit with the other TSA LAG rules? From the other posts on this thread, I thought that flasks were okay as long as they were small enough.
If your flask contains liquid, then it must conform to the rules for liquids - < 100 ml volume, must fit in your Idiot Bag. I'd suggest not running afoul of any local liquor/open container ordinances. TSA loves to tattle to law enforcement. Sealed 50ml liquor minis are not a problem.
If your flask is empty, it's just like an empty water bottle - permitted.
