Getting through security at the airport is difficult especially if you are not aware of all the rules and regulations put in place. There is a rule that the TSA has put in place regarding liquids and gels. The method is the 3-1-1 method. The 3 is for 3 oz. containers or less, 1 is for 1 quart sized clear zip-top bag to hold the 3 oz. containers, and 1 is for one clear bag per person. Keeping in mind the 3-1-1 method will make it a lot easier to get through security without too much delay.
There are exceptions to the 3 oz. rule as long as you declare them at the security check point. Breast milk, formula, juice, milk and liquid prescription medications are examples of what is allowed over 3 oz. These items are not required to be in a zip-top bag.
Being aware of the 3-1-1 rule makes moving through security less hectic for you and everyone behind you in line. If you do not have to carry liquids or gels on the plane with you, then you should pack them in your check in luggage. The advantage is they can remain in their original packaging and you don't have to measure or buy special container's to hold them. If you pack your liquids and gels in your checked luggage, you also don't have to have them in zip-top bags.
