Flights from Incheon Intl to the United States: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Incheon Intl to the United States 
tonyFlew with AIR PREMIA-Jul 2026
Air Premia is a great option. Paying for premium is worth the extra money. Additionally try to check in online if possible.
Verified travelerFlew with Animawings-Apr 2026
Wear compression socks, walk around every 1-2.5hrs to allow blood flow.
Verified travelerFlew with AIR PREMIA-Jan 2026
Get a mobile boarding pass ahead of time. Also, register for the Smartpass (requires an app) for a shorter line at the security.
Verified travelerFlew with Hawaiian Airlines-Mar 2025
The connection to the next flight can be difficult. We got lost in the Incheon Airport trying to transfer to Terminal 1, and almost missed our flight since it was very difficult to find instructions on how to get there. I suggest finding instructions how to transfer to the connecting flight in Incheon Airport.
Verified travelerFlew with Asiana Airlines-Mar 2025
Be careful to allow enough time when going thru Customs & Immigration. Despite having Global entry privileges, we missed our connecting domestic flight because luggages arrived late before we got thru Customs. Then, we have to contend with long security lines in SEA.
Verified travelerFlew with Korean Air-Dec 2024
Fly Korean Air if you can. ICN is a great airport and you won't have any issues getting through in a reasonable time, but be aware that the gates for US-bound flights are fairly far away.
highoutputFlew with Korean Air-Jan 2025
Wear comfortable clothes. Bring whatever you need to be comfortable
Verified travelerFlew with Korean Air-Nov 2024
Incheon has always impressed me by its cleanliness so I invariably choose Korean Air over and above others. I appreciate the 2 free checked-in luggage policy. I find the weight limit for carry-ons plus personal item a bit restrictive. I bring a laptop with an AC adapter and that alone brings my carry-on weight close to the limit. Next time, I shall try not to bring other battery chargers (the ones that are not allowed to be checked in).
Verified travelerFlew with Korean Air-Oct 2024
If you are traveling with Korea Air and you think you want to have better seats, book it from the beginning. The run out of availability quickly
Verified travelerFlew with Hawaiian Airlines-Sep 2024
Avoid transit from one terminal to another. Takes 90 minutes to connect. Don’t waste money on Hawaiian Business Class. Not worth it.
ArthurFlew with Delta-Jul 2024
Get aisle seat and stretch legs every 2 hours minimum. Bring your own favorite snack .
HOJINFlew with AIR PREMIA-Aug 2024
Arrive during business hours so that the airport have enough staff to handle the arrival.
PlainFlew with Hawaiian Airlines-May 2024
Notify Airline of any precondition or current heath issues8, even if passage is alegic. Korean Air has an efficient boarding process. Less confusion. During my most recent flight a stewardess threw a beef tray mealin front me without a word.
