Most airlines have a standard size limit for carry-on bags, which is usually around 22 inches tall, 14 inches wide, and 9 inches deep. But, don't think you can sneak in a giant bag - they've got size checkers at the gate to catch you out! Some airlines are more lenient than others, so always check before you fly.
But, here's the thing - carry-on bag limit sizes aren't just about the size, they're also about the weight. Some airlines have a weight limit of around 40 pounds, while others are more relaxed. And, let's not forget about the liquids - you've got to follow the 3-1-1 rule or you'll be in trouble!
