Current security directives permit only three ounces or less of liquids or gels to go through security screening in one, quart-size, clear plastic, zip-top bag. With the exception of medications, any amount of liquid, including alcohol, greater than three ounces must be packed in your checked baggage.
However, after passing through the security checkpoint, you may now bring liquids and other items purchased in the secure boarding area onboard the aircraft.
If purchased in the secure boarding area, JetBlue will allow alcoholic beverages not more than 24% alcohol by volume, or more than 24% by volume and not exceeding 70% alcohol by volume, when in retail packages, not exceeding a total quantity of five liters per person.
