So, what else can you bring in your carry-on? Well, solid toiletries like toothpaste and deodorant are A-OK, but liquids and gels are a no-go if they're over the 3.4-ounce limit. And, let's not forget about the exception to the exception - some medical devices like insulin pumps and epipens are allowed, but you'll need to declare them at security.
But, here's the thing - the TSA is all about flexibility. If you've got a special item that doesn't fit the 3-1-1 rule, you can always ask your TSA agent for help. They might just make an exception! After all, the TSA is all about keeping us safe, not about ruining our vacations!
