Japan Airlines Baggage Rules: Carry-On and Fees

On international JAL flights, you're allowed one main carry-on plus one personal item. The rule that catches people out: the sum of each bag's three dimensions (length plus width plus height, including handles and wheels) has to add up to 115cm (about 45 inches) or less, and the combined weight of both bags together can't exceed 10kg (22 lbs).

That 10kg combined weight limit is noticeably lighter than airlines with no published carry-on weight limit at all, like Delta or American. If your personal item, laptop bag included, already weighs 4 or 5kg, your main carry-on has very little weight budget left before you're over the line.

A practical way to plan around this: weigh your personal item first, since it's usually packed with heavier items like a laptop, charger, and a book, then subtract that number from 10kg to see what your actual carry-on suitcase has left. Packing light in the personal item, saving the weight budget for your main bag, is usually the easier way to stay under JAL's combined limit, since a rolling suitcase is easier to redistribute weight into than a backpack you're also wearing through the airport.

In Economy Class on JAL's North America and Hawaii routes, you get two checked bags free, each up to 23kg (50 lbs). That's a genuinely generous free allowance compared to most US domestic carriers, which charge for the first bag outright.

Beyond that free allowance, an additional checked bag on these routes costs 20,000 yen, roughly $200 USD. JAL's international fee and allowance tables vary by region, so the numbers above apply specifically to North America and Hawaii routes rather than JAL's full global network.

That two-bag free allowance is a genuinely different starting point than most US carriers offer on a comparable domestic route, where the first checked bag is rarely free outright. If you're connecting from a US domestic flight onto JAL for an international leg, don't assume the domestic airline's paid-first-bag rule carries over. Check JAL's own allowance for the international segment specifically, since the two legs of the same trip can run under completely different baggage rules.

On North America routes, a checked bag between 23kg and 32kg (roughly 50 to 70 lbs) adds an overweight fee of 10,000 yen, about $100 USD, on top of any bag fee already owed. Push past 32kg up to 45kg, and the overweight fee jumps sharply, to 60,000 yen, or roughly $600 USD.

That jump is steep enough that it's almost always cheaper to redistribute weight between two checked bags, or ship the extra weight separately, than to pay JAL's top overweight tier. Weighing your bag at home before you leave is worth the two minutes it takes.

Since you already get two free checked bags in Economy on these routes, the smartest move if one bag is running heavy is usually to shift a few items into your second bag rather than pay an overweight fee on the first. Splitting weight evenly across both free bags costs nothing extra and avoids the entire overweight fee structure, as long as you're not simply moving both bags over the 23kg line instead of one.

A lot of standard 21 or 22 inch carry-on suitcases, built for the US-style 45 linear inch, per-bag limit, will clear JAL's 115cm figure on their own. The catch is that JAL's 115cm and 10kg limits apply to your main bag and personal item combined, not per bag. A roomy laptop backpack used as a personal item can eat into that shared allowance fast.

If you're flying JAL internationally, weigh your carry-on and personal item together before you leave for the airport, not separately. That combined number is the one that matters at the gate.

JAL's 10kg combined carry-on and personal item weight limit sits in the same stricter range as Qatar Airways and Singapore Airlines, both of which cap Economy cabin baggage at 7kg per bag, and Iberia, which allows up to 10kg for its main hand luggage bag alone. British Airways is the outlier among these, publishing no cabin weight limit at all.

The practical takeaway: if you're used to flying a US carrier like Delta or American that publishes no carry-on weight limit whatsoever, don't assume that habit carries over to JAL. Weigh your bags before you leave home rather than finding out the number at check-in.

Everything above describes JAL's international baggage rules. Domestic flights within Japan run on a separate baggage allowance that isn't covered in this guide, so if your itinerary connects onward within Japan after an international JAL flight, check JAL's domestic baggage page specifically rather than assuming the international numbers above carry over unchanged.

If you fly more than just JAL, it helps to browse every airline's carry-on rules in one place, since JAL's combined-weight approach is genuinely different from how most US carriers measure a carry-on.

Our luggage size directory breaks down real bag dimensions pulled from actual product listings, which makes it easier to find a lightweight carry-on and personal item combination that clears JAL's 10kg total.
