So, when it comes to carry-on bags, you're allowed to bring a certain number of cigarettes on board, but be aware of the quantity limits. Typically, you can bring up to 200 cigarettes, but it's always best to check with your airline to confirm. And, don't even think about trying to sneak more on, you might get caught and that would be a real hassle!
Now, let's talk about packing those cigs safely and securely in your carry-on. You'll want to make sure they're in a sealed bag or container to prevent any accidents or spills. And, please, for the love of all things good, don't try to light up on the plane, that's just a big no-no!
