Delta opens a new gateway to Asia with first-ever nonstop route from Salt Lake City to Seoul

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.

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. This route—the only direct flight linking Salt Lake City to Asia—will provide seamless connections to key destinations across Asia for travelers throughout the Mountain West and Southwest U.S. regions. Customers will enjoy Delta’s state-of-the-art Airbus A350, along with modern amenities at SLC’s recently upgraded terminal and the expansive Delta Sky Club, ensuring a smooth and 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., have access not just to Seoul but to key destinations across Asia." 

Delta’s leading position at Salt Lake City 

As Delta’s fifth direct U.S. route to Seoul, the new SLC-ICN flight joins Atlanta, Detroit, Minneapolis-St. Paul, and Seattle in connecting U.S. travelers to Asia. With this addition, Delta—together with partner Korean Air—offers 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 further solidifies Delta’s position as the largest long-haul foreign carrier at Incheon, 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.” 
 
This historic route solidifies Delta’s leadership in Salt Lake City, where it operates more flights than all other carriers combined. Delta’s robust presence includes nearly 250 peak-day departures to more than 90 destinations worldwide, featuring nonstop service to other international cities like Amsterdam, London, Paris, and Mexico City, among others.  

Delta’s strong presence at SLC is further bolstered by ongoing investments in the airport’s infrastructure. In 2020, Delta celebrated the opening of the 900,000-square-foot Concourse A, featuring 50 Delta gates and 19 new restaurants and shops. By 2027, the airline will add even more gates, ensuring the hub remains a premier domestic and international gateway. 
 
Travelers passing through Salt Lake City can also indulge in Delta’s world-class amenities, including the 28,000-square-foot Delta Sky Club. Offering panoramic mountain views from the Sky Deck and a 360-degree fireplace, the lounge provides a relaxing haven for customers before they embark on 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 with 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 to Seoul 

The daily, year-round service to Seoul will be operated on Delta’s state-of-the-art Airbus A350-900 offering the latest in premium travel with Delta One Suites, Delta Premium Select, Delta Comfort+, and Main Cabin experiences. Travelers 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 customers in Delta Premium Select, wider seats, deeper recline, and elevated service create a more spacious and relaxing journey. Across all cabins, passengers can enjoy a curated food and beverage experience along with access to over 1,000 hours of entertainment via Delta Studio. 
 
Delta is also expanding its fast, free Wi-Fi presented by T-Mobile.

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.
