Delta Launches First-Ever Nonstop Service Between SLC and 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.

The daily, year-round service 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.

This route, which is 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.

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.

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.
