First of all, let's talk about size - most airlines have limits on how big your carry-on and checked bags can be. It's like trying to squeeze into a crowded elevator - if you're too big, you just won't fit. And, just like how you wouldn't want to be the one holding up the whole elevator, you don't want to be the one holding up the whole flight with an oversized bag.
Then, there's the issue of weight - you don't want to be like the friend who always brings too much stuff to the beach, only to realize they have to carry it all back home again. Most airlines have weight limits for checked bags, and if you go over, you'll have to pay a fee - it's like having to buy an extra slice of pizza just because you couldn't resist the temptation of that extra topping.
But, what about restricted items? You know, the things you shouldn't pack in your luggage, like lithium batteries or sharp objects. It's like trying to sneak a snack into the movie theater - you might get away with it, but it's not worth the risk of getting caught. And, trust us, you don't want to be the one who causes a scene at the airport security checkpoint.
