Japanese airlines on Tuesday will start enforcing size restrictions on domestic flight carry-on luggage in an effort to minimize delays caused by trying to stow items that are too big.
The overall dimension for carry-on baggage on aircraft that can seat 100 or more passengers must not exceed 55 cm by 40 cm by 25 cm.
For aircraft that seat 100 or fewer passengers, the dimensions must measure no more than 45 cm by 35 cm by 20 cm.
