The reason airlines have size restrictions on carry on bags is to make sure everyone has enough space in the overhead bins. Imagine if everyone had a giant bag - it would be chaos! So, it's all about finding that balance between bringing what you need and not overdoing it.
Now, you might be wondering, what's the best way to measure your bag to make sure it fits? Well, most airlines have size checkers at the gate, but you can also measure your bag at home to be sure. Just grab a tape measure and get to work - it's not rocket science, but it can save you some hassle at the airport.
So, what happens if your bag is too big? Don't worry, it's not the end of the world - you'll just have to gate check it, which means you'll drop it off at the gate and it will be waiting for you at the baggage claim when you land. It's not ideal, but it's better than having to pay for checked baggage!
