Japan Airlines (JAL) Carry-On Rules: Economy to First
Japan Airlines (JAL): Cabin size, personal item and class limits.
Cabin allowance
All cabins allow one main bag and one personal item, with a combined limit of 10 kg. Business and First do not add a second main bag. The main bag must meet both 55×40×25 cm and a total of 115 cm, including wheels and handles. A 55×40×25 cm case totals 120 cm and fails; 55×40×20 cm totals 115 cm. Domestic aircraft with fewer than 100 seats use 45×35×20 cm and 100 cm total. Check the aircraft on every segment; the calculator uses the international/large-aircraft rule.
JAL requires the personal item to fit under the seat but does not publish a numeric personal-item box on the reviewed page. Do not borrow ANA’s dimensions as a JAL guarantee. Weigh both items together: 8 kg plus 3 kg exceeds 10 kg. Airport purchases count in the allowance.
Before departure
Measure the packed bag and weigh all items before leaving. Check the operating carrier for codeshares and every connecting flight. Cabin space is not guaranteed even for compliant bags. Resolve excess at check-in and request the price for your actual itinerary; no universal gate fee or free exception is promised. Confirm infant tickets, child equipment and liquid screening separately. The calculator does not identify aircraft, total several bags or confirm a special arrangement.
