Asiana caps your carry-on bag at 10 kg, not just a size. Most US airlines only check whether your bag fits the sizer. Asiana weighs it too, and 22 lb is a tight number for a bag full of gear.
That single detail sets the tone for the whole Asiana baggage allowance.
The Asiana baggage allowance starts with a total, not a box
Asiana does not hand you three box dimensions to memorize. It adds length, width, and height together. The total has to stay under 115 cm, about 45 inches.
That works out close to a 21.7 x 15.7 x 9.1 inch bag. The airline leaves the exact shape up to you as long as the sum holds.
Economy passengers get one carry-on bag. Business class gets two. Either way, the 10 kg weight cap applies to every bag, and gate agents do check it.
The personal item is smaller than you think
Your personal item has to fit inside 40 x 30 x 20 cm. That is about 16 x 12 x 8 inches.
That is a laptop bag or a small handbag. It is not a backpack you are trying to sneak past the carry-on rule.
One personal item is allowed per passenger, in every class, under the seat in front of you.
Asiana baggage allowance: the checked bag advantage
Economy passengers on US routes get two free checked bags. Each can weigh up to 23 kg, about 50 lb.
Each bag has to total under 158 cm, roughly 62 inches, adding length, width, and height. Business class gets two free bags up to 32 kg each, and first class gets three.
There is no separate charge for the first or second bag in economy. That holds as long as both stay inside those limits.
What happens when you go over
Standard US routes cover Asia to the US, Europe to the US, and Oceania to Saipan. On those routes, an extra bag or an oversize one costs 200 USD. Check Asiana’s own baggage page for current pricing before you fly.
A bag between 24 and 32 kg adds another 100 USD. One between 33 and 45 kg adds 400 USD instead.
Oversize bags follow their own scale. Expect 200 USD for 158 to 203 cm, and 400 USD for anything larger.
On the Asia to Saipan route, most of those fees drop by half.
Golf bags get a pass, other gear does not
Asiana lets you check one golf bag free, even past your normal piece count. It can still cost extra if it is overweight.
Snowboards and bicycles travel free too, but only inside your existing allowance. Musical instruments over 115 cm need their own seat.
What travelers actually run into at the gate
Travelers on FlyerTalk describe the 10 kg carry-on cap in the Asiana baggage allowance as real but unevenly enforced. One traveler who arrived a couple of kilos over paid an overage fee on the spot rather than getting waved through, and noted the outcome came down to the ground crew working that flight.
Forum discussion also clears up a point of real confusion. The 115 cm figure is a combined total across your carry-on pieces, not a limit checked bag by bag, and travelers report that a bag pushing the total over that line gets pulled at the gate and checked instead.
The pattern travelers describe is consistent: do not count on talking your way past the limit. Enforcement depends on who is working the counter that day.
What we could not confirm
Asiana spells out its weight and size overage fees clearly. A flat fee for a third checked bag on US routes was not listed anywhere we could reach.
If your trip needs a third bag, call Asiana or ask at the counter. Do not trust a number nobody has verified.

The bottom line
The Asiana baggage allowance rewards economy flyers with two free checked bags on US routes. That beats what Delta and most US carriers include.
The tradeoff is a strict carry-on weight limit. Peers like Singapore Airlines and Cathay Pacific enforce the same rule, but many US airlines skip it entirely.
Run your bag through our size checker before you pack. Use the baggage cost calculator to see what a third bag might run you elsewhere.
