Korean Air and Delta Expand Bag Transfers at LAX and Seattle, Easing U.S.-Asia Connections

Korean Air and Delta Air Lines have expanded their Seamless Baggage Transfer program to two of the most important U.S. gateways for Asia travel, giving eligible passengers arriving from Seoul Incheon a simpler connection process at Los Angeles and Seattle. The change, which went live on June 23, 2026, matters because it targets one of the most frustrating parts of entering the United States on a connecting itinerary: collecting checked bags, clearing inspection and rechecking them before the next domestic flight.

The expanded service now covers flights from Seoul Incheon International Airport (ICN) to Los Angeles International Airport (LAX) and Seattle-Tacoma International Airport (SEA). Those airports join Atlanta, Detroit and Minneapolis-St. Paul, creating a five-gateway U.S. network for the Korean Air-Delta joint venture.

What changed for travelers

Under the usual U.S. international arrival process, travelers with onward domestic flights often have to retrieve checked bags at the first U.S. airport, clear Customs and Border Protection procedures, and place the luggage back into the airline system before heading toward security and the connecting gate. Seamless Baggage Transfer is designed to remove that extra bag-handling step for qualifying itineraries.

The program uses International Remote Baggage Screening technology. In practical terms, checked baggage is screened before the aircraft reaches the United States, with baggage information reviewed through a process involving U.S. authorities. For eligible passengers, the bag can continue to the final destination without the traveler personally reclaiming it at the first U.S. gateway, unless officials require additional inspection.

Delta says the service is now live on Incheon-Seattle and Incheon-Los Angeles flights operated by Delta and Korean Air. Travel trade reports citing the airlines say the expansion can save travelers up to about 20 minutes during a U.S. connection. Earlier Delta materials described average time savings of up to 25 minutes on other participating Incheon-U.S. routes.

Why LAX and Seattle make the expansion more important

The addition of Los Angeles and Seattle is significant because both airports are high-volume West Coast entry points for Asia traffic. LAX is one of the country’s busiest international gateways and a major connecting point for travelers continuing to cities across California, the Southwest, Mountain West and Latin America. Seattle is a key Delta gateway with strong trans-Pacific demand and onward connections across the Pacific Northwest, Alaska and the broader U.S. network.

For U.S. travelers returning from Korea, Japan, Southeast Asia or other points that connect over Seoul, the improvement can make the most stressful part of the trip a little more predictable. It may be especially useful for families, older travelers, premium leisure passengers, business travelers with tight schedules and anyone connecting after a long-haul overnight flight.

The change also shows how airlines are competing on airport experience, not only on routes and aircraft. Trans-Pacific flights are long, and many U.S.-Asia itineraries involve at least one connection. A smoother bag process can make a Seoul connection more attractive when travelers are comparing options through Tokyo, Taipei, Hong Kong, Vancouver or other gateways.

The five U.S. gateways now covered

With the latest rollout, Korean Air and Delta’s Seamless Baggage Transfer network from Incheon now includes:

Passengers should still check the exact rules for their itinerary. Korean Air’s own transfer guidance says baggage connection can be limited by destination, airline and ticketing conditions, and separately ticketed trips may not receive the same automatic handling. Travelers should confirm at check-in that their bag tag shows the final destination and that the itinerary qualifies for the program.

What this does not change

The new process does not mean travelers can ignore U.S. entry procedures. International passengers still need to meet passport, visa or ESTA requirements where applicable, follow CBP instructions and clear any required screening. If authorities refer a passenger or bag for additional inspection, the usual process can still take longer.

It also does not erase the need for sensible connection buffers. LAX and Seattle can both face peak arrival waves, weather issues, long walks, security lines and terminal-transfer complexity. Travelers using the new service should still monitor the LAX online flight board or Seattle flight board before and during travel, especially when arriving from Asia and continuing on a separate domestic plan later the same day.

For travelers ending their trip at the gateway, ground transport planning remains just as important. At Los Angeles, airport construction, traffic and ride-hail pickup rules can add time after a long flight, making LAX airport transfer planning useful. At Seattle, passengers heading downtown, to the Eastside or to cruise connections should compare transit, taxi, shuttle and rental-car timing through the SEA airport transfer guide.

What U.S. travelers should do now

For Americans booking Asia trips through Seoul, the update gives the Korean Air-Delta partnership a more concrete convenience advantage at the airport. It is most valuable when the full trip is on one ticket, the passenger is connecting onward in the United States and the bag is tagged all the way to the final city.

Before departure, travelers should verify three things: whether their flight is one of the participating Incheon-U.S. services, whether the onward connection is protected on the same ticket, and whether the checked bag is tagged through to the final destination. During summer and holiday periods, it is still wise to leave more room than the minimum connection time, because a smoother baggage process cannot prevent late inbound flights, immigration queues or weather-related delays.

For the U.S. travel market, the bigger takeaway is that international connection quality is becoming a selling point. As airlines add more Asia capacity and compete for higher-yield leisure and business travelers, small airport-process improvements can influence which hub feels easiest to use. Korean Air and Delta’s expansion to Los Angeles and Seattle does not make U.S. arrivals effortless, but it does remove a familiar pain point from more trans-Pacific journeys.
