Korean Air and Delta Air Lines are expanding Seamless Baggage Transfer from Incheon International Airport outside Seoul to Seattle-Tacoma International Airport and Los Angeles International Airport. According to an announcement, the expansion “further enhances the travel experience for customers flying from Korea to the United States by saving up to 20 minutes when connecting in the US.”

Seamless Baggage Transfer, powered by International Remote Baggage Screening technology, allows checked baggage to be screened prior to arrival in the US, eliminating the need for customers to collect and recheck bags during connections. With this expansion, Seamless Baggage Transfer is now available across five major US gateways: Atlanta, Minneapolis-St. Paul, Detroit, Seattle and Los Angeles. This includes Korean Air and Delta customers connecting through Incheon from across Asia to these five US cities.

Using advanced X-ray screening technology, according to the announcement, baggage is screened at Incheon and securely reviewed by U.S. Customs and Border Protection before the flight lands. Customers can proceed directly to their connecting gate, similar to a domestic transfer, while their bags are automatically transferred to their final destination, saving up to 20 minutes.

Since its introduction on Incheon-Atlanta flights in August 2025, Seamless Baggage Transfer, said the announcement, has proven to significantly elevate passenger convenience. Notably, said the announcement, it has cut customs interactions at US airports by over 65%. In situations when an unexpected late arrival would have caused customers to miss their connections under the previous baggage recheck process, it has enabled a vast majority of customers to successfully catch their onward flights.

Kwangho Ko, senior vice president at Korean Air, said, “Our joint venture with Delta continues to strengthen connections between Korea and the United States.” Together, he said, “we are building a more connected global network through Incheon, giving customers greater convenience, more choices and a consistently elevated level of service throughout their journey.”

Jeff Moomaw, vice president – Asia Pacific for Delta, said, “Seamless Baggage Transfer simplifies the connection experience for customers traveling to the United States.” By expanding this service to Seattle and Los Angeles, he said, “we enable customers to move through US airports more efficiently and have more time to relax between flights.”
