Most airlines have similar size restrictions for carry-on bags. Typically, the maximum dimensions are 22 inches long by 14 inches wide by 9 inches deep, this includes all handles and wheels. If you're unsure about the size of your bag, it's always best to check with your airline before you travel. They may have specific requirements that are different from other airlines. By following these guidelines, you can be sure that your carry-on bag will be the perfect size for your next flight.
