Delta Air Lines and Korean Air are expanding codeshare flights, following the launch of a joint venture partnership May 1 that gives customers world-class travel benefits across one of the most comprehensive route networks in the trans-Pacific market.

A total of 132 Delta-operated flights from Seattle, Atlanta, Las Vegas, New York, San Francisco, Honolulu, Chicago and Dallas have been recently coded with Korean Air’s flight number. These new codeshares complement 164 existing Korean Air codeshare markets on Delta in the Americas from Delta’s hubs in Atlanta, Los Angeles and New York-JFK. An additional 66 markets from Detroit, Portland, Seattle and Atlanta will become codeshares in North America next week. In addition, Korean Air’s code will be added to five Delta-operated flights from Japan to Atlanta, Detroit, Seattle and Portland, beginning June 6.

The enhanced codeshare flights in the Americas will further strengthen the existing 36 codeshare routes within Asia.

“Expanding our codeshares in the U.S. is another step to building the best trans-Pacific partnership for our shared customers,” said Matteo Curcio, Delta’s Vice President – Asia Pacific. “Our combined network and schedules give customers in the U.S. and Asia significantly enhanced choices.”

Earlier this year, Delta and Korean Air co-located at the new, state-of-the-art Terminal 2 of Seoul’s Incheon International Airport, substantially reducing connection times for customers. Since April, Delta and Korean Air have been codesharing on each other’s Seattle–Incheon flights, significantly increasing customer choice and connectivity. Both airlines have also improved their loyalty programs’ reciprocal benefits, including the ability to earn more miles on both loyalty programs and redeem them on the increased codeshare flights.

Delta and Korean Air continue to work closely to implement full reciprocal codesharing on each other’s networks to the extent allowed and provide the best travel experience for customers between the U.S. and Asia.

Delta is investing in the Asia-Pacific region where it has seen a steady increase in customer satisfaction as more Asia-based customers choose to fly Delta. Some of the investments include expanding its Asia-Pacific network, developing strong partnerships with important Asian carriers like Korean Air, operating Delta's first Airbus A350s into Asian markets featuring the all-new Delta One suite product enhancement and Delta Premium Select cabin, upgrading complimentary economy cabin amenities and more.
