Visit delta.comStrategically connecting Asia and the Americas: Delta at Incheon International Airport
Learn how Delta Air Lines leverages its connections with its Incheon International Airport hub as Northeast Asia's No. 1 hub.
Incheon International Airport (ICN) serves as a crucial gateway between the Americas and Asia and is one of the world’s busiest transportation hubs. With Incheon as its major Asia-Pacific hub, Delta operates more nonstop routes than any other non-Asian airlines.
ICN connects the U.S. with Hong Kong, Thailand, Vietnam, and other destinations in Asia with the key partnership of Korean Air and Delta’s JV agreement. Delta and Korean Air offer 18 flights a day transporting over 2,000 passengers daily to destinations across Asia, connecting 290 destinations in the Americas and 80 destinations in Asia. Delta and Korean Air have aligned products and services to ensure a seamless, consistent and industry-leading customer experience.
Together, Delta and Korean Air have earned the trust of both Asian and American customers to become the No. 1 trans-Pacific joint venture.
In 2024, Incheon International Airport also served as Asia's No. 1 hub airport last year, with approximately 70 million connecting passengers in total, approximately 2.61 million passengers traveling routes to the Americas (including Canada), showing a high transfer rate of 36.1%.
In December 2024, ICN expanded Terminal 2 and added a new runway, boosting its annual flight capacity from 500,000 to 600,000 and increasing the airport's overall capacity to 160 million passengers. The airport is also enhancing its facilities for travelers, with innovations like autonomous transportation and simplified check-in process through kiosks. ICN also provides special passenger experience beyond traveling by creating an art space ‘Art-Port,’ an outdoor park and the Korean Traditional Culture Center.
An increase in airport capacity has not resulted in longer wait times, thanks to new technology. With the introduction of Smart Pass technology, an optional identification process that leverages facial recognition, passengers can complete immigration procedures without passports or boarding passes, reducing wait times by up to 40%.

Delta Air Lines currently operates 35 weekly flights to ICN from Atlanta, Detroit, Minneapolis and Seattle. In June, the airline will launch its first-ever nonstop route from Salt Lake City International Airport (SLC), which will be the only direct flight linking SLC to Asia. This new route is expected to strengthen connection between major hubs in Asia and the U.S. Delta plans to operate the SLC-ICN route seven times per week, increasing weekly flights from the U.S. to ICN to 42.
By integrating Delta's unparalleled connectivity with ICN's optimized operational system, Delta will not only continue to offer its passengers more flight options and exceptional customer experience, but also provide the best travel experiences to our customers around the world.
Delta is boosting its global footprint with the launch of its first-ever nonstop service from Salt Lake City International Airport (SLC) to Seoul-Incheon International Airport (ICN) on June 12, 2025.
