I'm really not sure, as I don't carry medicines that are liquids with me. I first learned about the no-liquid policy flying in on UA SFO-PEK about a week ago. The FAs were first hearing about it. Returning, PEK-SFO, I did notice a woman in front of me having a discussion with the security folks over what looked to be a nasal spray of some sort. Or maybe eye drops. Not sure. Looked to me like she lost the debate, and it was confiscated.
