Frequently asked questions
What happens if my bag is overweight at Incheon Airport?
You pay an excess baggage fee at check-in — roughly $7–12 per extra kg on Korean budget airlines, or a flat per-bag fee (often $100–200) on US and long-haul routes. Repacking into a second bag is usually far cheaper than paying overweight fees, so weigh your suitcase before heading to the airport.
Do airlines at Incheon actually weigh carry-on bags?
Yes — Korean and Asian budget airlines routinely weigh cabin bags at check-in and sometimes again at the boarding gate. Full-service Asian and European carriers enforce limits more loosely, while US carriers (United, Delta, American) have no cabin weight limit at all, only size checks.
Which terminal does my airline use at Incheon Airport?
Terminal 2 serves Korean Air, Asiana, Jin Air, Air Busan, Air Seoul, and SkyTeam members such as Delta, KLM, Air France, China Eastern, Xiamen Air, Vietnam Airlines, Garuda Indonesia, and China Airlines. Almost all other airlines depart from Terminal 1. Always confirm the terminal printed on your e-ticket — the two terminals are 15–20 minutes apart by shuttle.
What do the “158 cm” and “115 cm” size limits mean?
They are the sum of a bag’s length + width + height. 158 cm (62 in) is the standard checked-bag limit — a 28-inch suitcase fits under it — while 115 cm (45 in) is the common carry-on limit, which matches a 20-inch cabin suitcase.
Can I bring a personal item in addition to my carry-on?
Most full-service airlines allow one cabin bag plus one personal item such as a laptop bag or small backpack. On many budget carriers — AirAsia, Jetstar, Scoot, and others — both items together must stay within the 7 kg cabin allowance.
My suitcase is too small or broken — where can I get a new one in Seoul?
Unboxing Korea delivers brand-new hard-shell suitcases (20″, 24″, and 28″) directly to your hotel in Seoul, often same-day, with no Korean phone number or local card required — handy if you’ve shopped more than your bag can hold before flying out of Incheon. Order a suitcase →
