When it comes to carry on bags, most airlines have pretty similar rules, but it's always a good idea to check with your airline before your flight. Generally, a carry on bag can be up to 22 inches tall, 14 inches wide, and 9 inches deep - but who's got a ruler handy, right? It's more about common sense and making sure your bag fits in the overhead bin or under the seat in front of you.
Now, let's talk about backpacks - are they carry on bags? Well, it really depends on the size of your backpack. If you've got a small to medium-sized backpack, it's probably going to be just fine as a carry on. But, if you've got a huge backpack, like one that's meant for hiking or camping, it might be too big for the overhead bin.
Think of it like trying to squeeze into a pair of favorite jeans from high school - if it's too tight, it's just not going to work. Same thing with your backpack and the overhead bin. If it's too big, you might have to check it, which can be a real bummer. But, if you've got a smaller backpack, you're probably golden - just stuff it in the overhead bin and you're good to go!
