Jeju Air Carry-On Rules: Size, Weight & Allowances (2026)

Jeju Air includes one main bag up to 55 × 40 × 20 cm and one personal item up to 40 × 30 × 15 cm, with 10 kg combined. Duty-free purchases count within these limits. Ten kilograms is not an allowance for each bag.

Size and weight at a glance

For example, an 8 kg main bag leaves 2 kg for the personal item and permitted shopping. Moving things between the bags does not reduce the total. The published common policy does not offer a 15 kg cabin upgrade on higher fares; checked baggage allowances are separate.

Measure the packed exterior, including protruding parts, conservatively. The reviewed page does not explicitly define wheels and handles. Litres and a suitcase's advertised inch size do not prove that the packed bag fits.

Use the checker

Enter your actual dimensions and weight in the Jeju Air checker. It assesses one bag, so also weigh both permitted items together. For another operating airline on the trip, use the route checker; a Jeju allowance does not cover a separately operated segment.

At the gate and checked baggage

Excess cabin baggage must be checked. Jeju lists a boarding-gate handling charge per item of KRW 10,000 / USD 10 domestically and KRW 20,000 / USD 20 internationally, collected in the local currency of the origin. Applicable excess-baggage charges depend on the trip; these amounts are not a complete universal checked-bag quote. Obtain the price for your booking in advance.

Even a compliant bag may go in the hold if cabin space or operational circumstances require it. No reliable check-in or gate weighing frequency is established. Do not count on a particular airport overlooking an overweight bag.

BASIC, STANDARD and BIZ LITE have different checked allowances, and Guam/Saipan use separate tables. A checked-baggage benefit does not increase the common cabin limit.

Infants and equipment

Jeju permits one fully foldable stroller, infant bassinet or car seat as the infant-equipment allowance. A compact flat-folding stroller may enter the cabin when its three dimensions total no more than 115 cm. Confirm acceptance and handover with the airline; a car seat's permission for transport does not prove it is approved for use in a passenger seat.

Drop-off may be at check-in or the gate, and collection at the arrival gate or baggage claim. Airport conditions can prevent gate handover or pickup. The optional paid Doorside quick-pickup service is separate. Infants without a seat have no ordinary free domestic checked allowance; international conditions depend on fare and route.

Liquids

Korean international security applies the usual 100 ml container / one-litre clear resealable bag rule to ordinary liquids. Domestic ordinary liquids are exempt from that volume rule. Dangerous-goods restrictions still apply, and international connections or duty-free purchases need their own security check.
