Can you bring multiple 3 oz bottles on a plane?

Yes, put it in your transparent small package, about 3-5 are all OK.

3-1-1 for carry-ons = 3 ounce bottle or less; 1 quart-sized, clear, plastic, zip-top bag; 1 bag per passenger placed in screening bin. One-quart bag per person limits the total liquid volume each traveler can bring. 3 oz. container size is a security measure.
