If two adults and an elementary-school child each get a free 23 kg checked bag, the total is 69 kg. That doesn’t mean you can pack one suitcase at 30 kg and another at 39 kg. Whether you can pool a family checked baggage allowance depends on the airline, so check three things: weight concept or piece concept, whether family pooling is allowed, and the maximum weight per bag.
Korean Air: Don’t Pack Everything into One Bag

On Korean Air international economy routes (excluding the Americas and Brazil), the standard allowance is one bag up to 23 kg per person; Americas routes allow one or two 23 kg bags depending on fare. Korean Air states that you may not check bags on behalf of others or combine a group’s free allowance with your own. So a family of three with one 23 kg bag each should pack something like 22 kg, 21 kg and 20 kg. Even if the 63 kg total is under 69 kg, a single 30 kg bag can trigger overweight fees.
T’way Air: Pooling Allowed Under Conditions

T’way Air’s international conditions of carriage allow two or more passengers to have their combined free allowance treated as a group total when they request it and meet these conditions:
- Same flight.
- Same destination or stopover.
- Traveling together as one party.
- Checking in bags at the same place and time.
- Requesting pooling from the airline.
Even with pooling, per-bag maximum weight and size limits still apply, and allowances differ by fare and route.
Asiana Airlines: Check Pieces and Weight per Bag

For Asiana economy (regular members), non-Americas international routes allow one bag up to 23 kg, and Americas routes two bags up to 23 kg each, varying by membership tier, route and cabin. Check the number of pieces (PC) and per-bag limit on your e-ticket rather than just the total weight.
Do Kids Get the Same Allowance?

Many airlines give children with a purchased seat the same checked baggage allowance as adults. Korean Air gives children the adult allowance plus items like a folding stroller and car seat or bassinet, but promotional fares and codeshare flights can differ. Infants under 2 without a seat have a different allowance, so check separately.
How to Split Three Suitcases

Outbound: bag 1 for shared family clothes, bag 2 for parents’ clothes and toiletries, bag 3 for kids’ clothes, swimwear and medicines. Return: bag 1 for heavy liquids and cosmetics, bag 2 for clothes and shoes, bag 3 for souvenirs and light snacks. Aim for 20–22 kg per bag and leave a 1–2 kg margin, since airport scales can differ from yours.
Avoiding Excess Fees at the Airport

- Check the free allowance on your booking confirmation.
- Distinguish 15KG, 23KG, 1PC and 2PC notations.
- Check whether it’s a codeshare.
- Check whether family pooling is allowed.
- Weigh each bag at home.
- Separate items banned from carry-ons.
- Leave room for extra luggage on the return flight.
The family checked baggage allowance can vary by route and fare even on the same airline. A previous 23 kg allowance doesn’t guarantee the same on a new promo ticket.
Costs

Once you exceed your checked baggage allowance, fees vary by airline, route, number of pieces, weight and size, and piece, weight and size charges can apply together. If repacking at the airport isn’t possible, you’ll pay the counter rate, so compare prepaid baggage prices with airport prices on the airline’s website the day before.
Tips with Kids

- Don’t check passports or power banks in a child’s suitcase.
- Keep needed medicines in a carry-on.
- Pack a change of clothes in case bags are delayed.
- Spread everyone’s clothes across bags.
- Check size and weight limits for a carry-on your child pulls.
Pros and Cons of Splitting Bags

Splitting makes it easier to avoid overweight fees, leaves clothes for everyone if one bag is delayed and spreads souvenirs on the way home. On the other hand, there are more bags to move, taxi trunk space to consider and more bag tags to track.
Good to Know

Pooling a family checked baggage allowance is a service some airlines allow, not a universal right on all international flights; the same booking number doesn’t mean automatic pooling. On codeshares, the ticketing and operating airlines can differ, so check which airline’s baggage rules apply.
