Question: how many litres can you take on a plane?
Answer: These containers need to be packed in a durable, transparent, resealable plastic bag (e.g. a Ziploc freezer bag) that is no more than 20cm x 20cm in size and no more than 1 litre in capacity. Note: You can bring as many small containers as you want as long as they fit into the resealable plastic bag.
