The 3-1-1 rule is what the Transportation Security Administration (TSA) calls it - 3 oz or less of liquids, 1 bag per passenger, and everything must fit in a 1-quart zip-top bag. It's actually pretty simple once you get the hang of it. But, what about medications and special items - do they get a free pass?
It turns out that medications, baby formula, and breast milk are all exempt from the 3-1-1 rule. You can bring these items on board in reasonable quantities, but be prepared to explain what they are and why you need them. It's all about being prepared and communicating with the TSA agents.
Now, let's talk about checked luggage - the rules are a bit different here. You can pack larger quantities of liquids and gels in your checked bag, but be careful not to overpack or you might end up with a leaky mess. And, what about electronic devices - can you bring those on board?
