Hi, i was just wondering if anybody has flown to LA with cathay in the last month or two with a baby. Were you allowed to take water in a thermos on board? Did they make you dump the water at security? What about when you land in LA? Do US customs go through your liquids too? Any feedback would be greatly appreciated as i leave for LA this week and am nervous about the formula making on board if they dont allow me to take water! thanks!
