Korean Air’s baggage policy varies by cabin class and route. Economy passengers receive 1 checked bag (23 kg) on most international routes, while Prestige (Business) gets 2 bags (32 kg each) and First Class gets 3 bags (32 kg each). Carry-on is capped at 10 kg combined for Economy, 18 kg for Prestige and First.

Planning a Korean Air flight without reviewing the baggage policy first is a fast track to a nasty surprise at the check-in counter. Korean Air is South Korea’s flagship carrier and one of Asia’s largest airlines  but its baggage rules are stricter than most U.S. and European carriers in several key areas, including carry-on weight checks and a hard bag-refusal rule that no fee can override.

What Is Korean Air’s Baggage Allowance by Cabin Class?

Korean Air’s free baggage allowance depends on three factors: cabin class, route, and fare type. The table below summarizes the standard international allowances.

Domestic flights within Korea:

• Economy: 20 kg total
• Prestige: 30 kg total

Brazil update (June 30, 2025): Economy Saver tickets issued on or after June 30, 2025 now include only 1 bag at 23 kg  down from the previous 2-bag allowance.

What Is the Korean Air Checked Baggage Size Limit?

Korean Air enforces a maximum total linear dimension of 158 cm (62 inches)  measured as height + width + length, including handles and wheels  for all checked baggage on international flights. Every bag must stay within this size regardless of fare class.

The 32 kg (70 lb) per-bag weight cap is equally firm. On U.S., Canada, and Brazil routes, Korean Air will physically refuse any bag exceeding this limit. There is no fee that bypasses this rule. It exists to protect ground handlers from lifting injuries and is treated as a non-negotiable labor safety regulation. If a bag weighs 33 kg, the only options are to repack at the counter, pay for a second bag, or arrange Korean Air Cargo as a separate shipment.

Does Korean Air Use a Piece or Weight Baggage System?

Korean Air uses two separate systems, and mixing them up is one of the most common mistakes passengers make.

• Piece Concept: Applies to all flights touching the Americas (US, Canada, Mexico, Brazil, and Latin America). Your allowance is counted by the number of bags.
• Weight Concept: Applies to all other routes  Asia, Europe, Oceania, Middle East, and Africa. Your allowance is based on total weight across bags, subject to the 32 kg per-bag cap.

Practical tip: Check your booking confirmation’s “Free Baggage Allowance” line. If it lists a number of pieces, you’re on Piece Concept. If it lists kilograms, you’re on Weight Concept.

What Are Korean Air’s Carry-On Baggage Rules?

Korean Air allows 1 carry-on bag + 1 personal item in Economy and Premium, and 2 carry-on bags + 1 personal item in Prestige and First Class.

Economy/Premium carry-on dimensions:

• Carry-on bag: Max 55 cm × 40 cm × 20 cm (total linear ≤ 115 cm)
• Personal item: Max 40 cm × 30 cm × 15 cm (must fit under the seat)
• Combined weight: 10 kg maximum

Prestige/First Class:

• 2 carry-on bags at the same size limits per bag
• Combined weight: 18 kg maximum

Unlike most U.S. carriers, Korean Air staff frequently weigh carry-on bags at check-in and at the gate. The 10 kg limit is combined  your roller bag plus your laptop bag together cannot exceed it.

Backpack rule: A backpack that fits under the seat counts as your personal item. One that goes in the overhead bin counts as your carry-on. If you carry both a stuffed backpack and a roller suitcase in Economy, expect a problem at the gate.

What Are Korean Air’s Excess Baggage Fees?

If your bags exceed the free allowance in count, weight, or size, Korean Air charges excess baggage fees based on route. Here are the primary fee structures for international flights:

Extra bags (Americas routes, USD):

• 3rd bag (Economy/Prestige, Americas–Asia): $200
• 3rd bag (Brazil itineraries): $175
• 3rd bag (within Americas only): $75

Overweight fees (per bag, USD):

Oversized fees (per bag, USD):

Cost scenario example: An Economy passenger on a Seoul–Los Angeles flight checks 2 bags, each weighing 28 kg. The second bag is within the free allowance for Standard/Flex Economy (2 bags on Americas routes), but both bags are overweight. Each bag between 24–32 kg on Americas–Asia routes incurs a $100 overweight fee  bringing the total extra charge to $200.

Pre-purchasing excess baggage online through the Korean Air website or app is almost always cheaper than paying at the airport.

Musical instruments:

• Small instruments (violin, viola) with total dimensions under 115 cm (45 in) may be carried on board as carry-on, provided they fit in the overhead bin.
• Larger instruments must be checked or, if over 203 cm (80 in) or 32 kg, transported via a separate seat booking or cargo service.

• Key rule: If your sports bag and standard checked bag combined are within your weight allowance (e.g., 23 kg total), the oversized fee for the sports bag is waived  even if the bag exceeds 158 cm in linear dimensions.

How Does Korean Air’s Baggage Policy Compare to Competitors?

Korean Air’s carry-on weight enforcement is notably stricter than most U.S. carriers. Japan Airlines offers more generous checked baggage on most international routes for standard Economy fares.
