Delta Air Lines plans to increase non-stop service between Seattle Tacoma International Airport (SEA) and Seoul-Incheon International Airport (ICN) to 3-times-a-week.

The new increase starts Dec. 13th.

By providing the new service, Delta will be supplementing existing daily operations as well as their Joint Venture partner Korean Air's five-times-weekly flights. In total, there will be 15 flights a week available.

The airline will operate the flights on Airbus 330-900neo aircraft, which feature Delta One suites, Delta Premium Select, Delta Comfort+ and Main Cabin services.

“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 not only Seattle's largest global airline but also offers the most daily departures to nearly 50 destinations.

The new Seattle-Tacoma International Airport arrivals facility provides a much faster and comfortable experience for customers, with enhanced technologies for faster passport check clearance and reducing the average customer connection time by about 15 minutes.

You will see a lot more Asian route frequency increases as we approach 2023. The Asian markets desperately need the business on the backside of the pandemic.
