any liquid/foam/aerosol under 3.2 ounces is just fine. put all of them in a clear plastic bag (ex: zip lock) and put it in the front pocket of your carryon. when you get to the security check point, take the plastic bag out of your carryon and put it in one of the bins. you'll also have to take off your shoes and take your laptop out of your bag and place it in a bin.
this is the second travel related question you've posted. have you never been on a plane before? (or since 9/11?)
