Can i bring lotion in a carry on bag? If so does it have to be sealed?

Any liquid ... more than 100 ml not allowed. However small sizes lije travel po acks can be carried... with original wrap or brand on it.

Yes you can bring lotion but it can only be in a 3oz bottle size. (carry on size)

I usually put the lotion in a clear travel size container and then in a small zip lock bag. Container that meets the guideline (under 100 ml) can be easily purchased at lotion stores. I've carried shampoo, lotion, hand sanitizers, and etc. this way.
