Travel Carry on Liquid Size
So, what are the rules exactly? It's actually pretty simple: all liquids, gels, and aerosols need to be in containers that are 3.4 ounces or less. That's right, it's like the size of a small soda can. And, you need to put them all in a clear bag that can be sealed and opened easily.
But, why 3.4 ounces, you might ask? It's a great question, and the answer is that it's just the right size to make sure that everyone is safe, without being too restrictive. It's kind of like when you're packing a lunch, and you need to make sure you have enough food to last you the day, but not so much that it's overwhelming.

And, what about medications and baby formula? Don't worry, there are exceptions for those. It's like when you're playing a game, and you get a free pass - you can bring those items in larger quantities, as long as you declare them at security. But, it's always a good idea to check with your airline first, just to make sure.
