You can take an unlimited number of 100ml (or smaller) containers of liquids, aerosols, and gels in your carry-on luggage, but they must fit into one clear, resealable plastic bag of not more than 1 liter in capacity. The bag must be presented separately from your carry-on luggage during security screening. Make sure each item is within the size limit to avoid having to leave anything behind.
