Question: how much liquid can you bring on jetblue?
Answer: 3-1-1 for carry-on bags = 3.4 oz/100 ml bottle or less; one quart-sized, clear, plastic, zip-top bag; one bag per customer placed in screening bin. One quart-sized bag per person limits the total liquid volume each traveler can bring. The 3.4 oz/100 ml container size requirement is a security measure.
