Delta's Seoul Sojourn: SL to ICN Nonstop!

On June 12, 2025, Delta will launch its first nonstop service from Salt Lake City International Airport (SLC) to Seoul-Incheon International Airport (ICN). This route will be the only direct flight connecting Salt Lake City to Asia, providing convenient connections to various destinations across Asia for travellers in the Mountain West and Southwest U.S. regions. Passengers will have access to Delta's Airbus A350 and amenities at SLC's recently upgraded terminal and the expansive Delta Sky Club, ensuring a comfortable trans-Pacific journey.

“The launch of Salt Lake City to Seoul service offers customers convenient access to Delta’s growing global network and ensures that virtually all U.S. demand is connected to Seoul via nonstop or one-stop service,” said Joe Esposito, Delta’s Senior Vice President – Network Planning.

“As Salt Lake City continues to grow as a vital Delta hub, our strong joint venture with Korean Air allows us to offer unmatched connectivity between the U.S. and Asia, leveraging strong hubs on both sides. This ensures that customers, including those in the interior U.S., can access not just Seoul but key destinations across Asia." 

Delta’s leading position at Salt Lake City 

Delta's new SLC-ICN flight to Seoul is the airline's fifth direct route to South Korea from the U.S. The flight connects travellers from Atlanta, Detroit, Minneapolis-St. Paul, and Seattle to Asia. With this addition, Delta and its partner Korean Air now offer access to Seoul from 14 U.S. gateways, providing the most extensive reach across Asia through the ICN hub compared to any other trans-Pacific joint venture. This route also strengthens Delta's position as Incheon's largest long-haul foreign carrier, enhancing its already unmatched reach across Asia.

Lee Hag-jae, President of Incheon International Airport Corporation, shared, “I’m confident that Incheon Airport will continue to grow as a global hub through our partnership with Delta Air Lines. Together, we aim to set the standard for airline partnerships, sharing a vision of leading the global aviation market as a top-tier airport and airline.” 

Delta's strong presence in Salt Lake City solidifies its leadership. The airline operates more flights than all other carriers combined. The airline offers nearly 250 peak-day departures to over 90 destinations worldwide, including nonstop service to international cities such as Amsterdam, London, Paris, and Mexico City.

Delta has a significant presence at SLC and continues to invest in the airport's infrastructure. In 2020, Delta opened Concourse A, which spans 900,000 square feet and includes 50 Delta gates and 19 new restaurants and shops. By 2027, the airline plans to add more gates to maintain its status as a leading domestic and international gateway.

Travellers passing through Salt Lake City can enjoy Delta’s amenities, such as the 28,000-square-foot Delta Sky Club. The lounge offers mountain views from the Sky Deck and features a 360-degree fireplace, providing a retreat for customers before their journey to Seoul.

Utah Gov. Spencer J. Cox  said, “As we open this new gateway to Asia, I am excited to expand Utah’s global reach and foster new cultural and business partnerships. Delta’s commitment to our state underscores Utah’s growing role on the world stage. I was delighted to meet President Yoon Suk Yeol and discuss how this new route will deepen connections between Utah and Korea.” 

Salt Lake City Mayor Erin Mendenhall said, “Strong partnerships can often have the biggest impacts on visitors and our residents. From Delta’s Salt Lake City hub, the Incheon route will connect our capital city with 80-plus destinations in Asia, expanding our community’s global reach and what so many already know. Salt Lake City and the Mountain West are among the best places to visit and an even better place to call home.” 

World-class comfort in Seoul 

The daily, year-round service to Seoul will be operated on Delta’s Airbus A350-900. It offers the latest in premium travel with Delta One Suites, Delta Premium Select, Delta Comfort+, and Main Cabin experiences. Travellers can expect Delta’s renowned service and a uniquely premium onboard experience as they travel across the Pacific.

Delta One customers will enjoy a luxury experience with lie-flat seating, premium bedding, expanded beverage options, and a seasonal chef-curated four-course meal. As part of Delta’s new collaboration with Italian fashion house Missoni, Delta One passengers will receive exclusive amenity kits featuring luxury details that elevate their inflight experience. 

For passengers in Delta Premium Select, wider seats, deeper recline, and elevated service create a more spacious and relaxing journey. In all cabins, passengers can enjoy a curated food and beverage experience and access over 1,000 hours of entertainment via Delta Studio.

It is already available on 90 percent of domestic flights, and now they are introducing high-speed, streaming-quality Wi-Fi on long-haul international routes. The entire global fleet is expected to offer free Wi-Fi by the end of next year, making it easier than ever for SkyMiles Members to stay connected during their travels.
