Korean Air hand luggage and cabin bags by fare
What each ticket type includes, as published by Korean Air.
| Fare | Under-seat bag | Cabin bag |
|---|---|---|
Economy and Premium Economy
| Included 40 × 30 × 15 cm A handbag, briefcase, laptop bag or similar. Its weight counts towards the 10 kg limit for both bags together. | Included 55 × 40 × 20 cm · 10 kg A carry-on suitcase, backpack or Boston bag. It passes if all three sides add up to 115 cm (45 in) or less, or if it is within 55 × 40 × 20 cm, including handles and wheels. The 10 kg limit covers this bag and the personal item together. |
Korean Air measures the whole bag, including wheels, handles and pockets.
If your bag is too big at the gate
A carry-on bag that is too heavy for the overhead bin should be checked in. Even a bag within the limits may be checked at the gate if there is no room on board.
It’s almost always cheaper to add the right bag when you book or online before you fly.
Other Korean Air cabin rules worth knowing
- On codeshare flights the carry-on allowance may follow the operating airline's rules.
- Carry-on allowances can vary for some countries because of national and airport rules.

Liquids rules by airportKorean Air cabin bag questions
What size is Korean Air’s free under-seat bag (personal item)?
40 × 30 × 15 cm on the Economy and Premium Economy fare. It must fit under the seat in front of you.
What size cabin bag can I take on Korean Air?
Up to 55 × 40 × 20 cm and 10 kg. It’s included with Economy and Premium Economy.
Do Korean Air’s size limits include wheels and handles?
Yes. The limits are for the whole bag, including wheels, handles and side pockets.
What is the Korean Air hand luggage weight limit?
The cabin bag can weigh up to 10 kg. Korean Air’s published rules give no weight limit for the free under-seat bag.
What happens if my bag is too big for Korean Air?
A carry-on bag that is too heavy for the overhead bin should be checked in. Even a bag within the limits may be checked at the gate if there is no room on board.
What are the Korean Air cabin bag dimensions in inches?
Free under-seat bag (40x30x15 cm): 15.7 × 11.8 × 5.9 in. Cabin bag (55x40x20 cm): 21.7 × 15.7 × 7.9 in.
How many litres is the Korean Air cabin bag allowance?
At most 18 litres for the free under-seat bag (40x30x15 cm) and at most 44 litres for the cabin bag (55x40x20 cm). That is the volume of a square-cornered box with exactly those measurements. A real bag has rounded corners, so check the size on the label as well as the litres.
