Question: how many oz are you allowed to take on a plane?
Answer: Any liquids, gels and aerosols in containers larger than 100 ml / 100 grams (3.4 oz) should be placed in checked baggage, as long as they are not prohibited items. Avoid packing gifts and souvenirs containing liquids, aerosols and gels in your carry-on. Put them in your checked baggage or ship them separately.
