So, what's the magic number when it comes to carry-on size? Most airlines agree that a bag should be no larger than 22 inches tall, 14 inches wide, and 9 inches deep. But don't just take our word for it - it's always a good idea to check with your airline before your flight to make sure you're in the clear. After all, you don't want to get stuck at the gate, forced to gate-check your beloved bag.
Now, you might be thinking, "But what about all my essentials - my laptop, my hairbrush, my favorite sweatshirt?" Fear not, friends! With a little creative packing, you can fit all your must-haves into a carry-on of the perfect size. Just remember, it's all about rolling your clothes and making the most of that sweet, sweet carry-on real estate.
