The reason we should all care about max airline carry-on size is that it affects our travel experience. Think about it - if your bag is too big, you might have to gate-check it, which means you'll have to wait for it at the baggage claim after your flight. And who wants to wait around after a long flight, when you could be relaxing in your hotel room or exploring the city?
A good way to think about carry-on size is to compare it to a large backpack. Most airlines allow bags that are around 22 inches tall, 14 inches wide, and 9 inches deep - roughly the size of a big backpack. So, if your bag is smaller than that, you're golden! But if it's larger, you might need to check it, which can be a hassle.
Now, you might be wondering - what's the consequence of having a bag that's too big? Well, aside from having to gate-check it, you might also be charged an extra fee by the airline. And who wants to pay extra money for something that's avoidable? It's like getting a parking ticket - frustrating and unnecessary!
