Delta adds second Seoul service in December, complementing existing daily operation


Delta Air Lines will increase the frequency of its nonstop service between Seattle-Tacoma International Airport and Seoul-Incheon International Airport with the addition of three-times-per-week service effective Dec. 13. The new service will complement Delta’s existing daily operations and Joint Venture partner Korean Air’s five-times-weekly service, bringing the total frequency to 15 flights a week.

Delta’s Seoul services will operate on the latest Airbus 330-900neo aircraft, featuring Delta One suites, Delta Premium Select, Delta Comfort+ and Main Cabin services. The added service will also provide new time channel option for customers connecting to Asia via Incheon, the joint venture’s hub.

“Korea travel demand has strongly rebounded since the reopening in April, leading recovery in Asia,” said Matteo Curcio, Delta’s Vice President - Asia Pacific. “With our increased flights between Incheon and Seattle, more passengers will be able to enjoy our best-in-class travel experience during the winter travel season.”

Delta is Seattle’s largest global airline and serves more international destinations than any other carrier, offering more than 130 daily departures to nearly 50 destinations across the globe. The Seattle-Tacoma International Airport recently opened a new, stunning 450,000-square-foot International Arrivals Facility (IAF) in May, offering customers a faster, more comfortable experience, with enhanced technologies for faster passport check clearance and reducing the average customer connection time by about 15 minutes.
