Am i allowed to take makeup powder on a domestic flight?
Powdered makeup is allowed in your carry-on bag on any domestic flight in the US. As for the question on liquids, the TSA’s website, which has the details on the liquid restrictions in carry-on bags, notes that you are allowed as many containers of 3.4 ounces (100mL) or less as will fit into your quart-sized ziploc bag, so long as the bag will still completely close.
