Korean Air, in a joint venture with Delta Air Lines, today launched non-stop flights between Boston and Seoul.

The first flight that arrived today at 10:33 a.m. local time from Seoul Incheon was saluted by a water cannon and celebrated in speeches by airline and government officials. Then Korean Air distributed mementos and offered refreshments to all the passengers on the first flight out of Boston at 1:36 p.m.

“Korean Air is the largest Transpacific airline and we’ve been eyeing Boston for a long time,” said the airline’s Vice President of Marketing, John Jackson. “It makes sense, with our Delta joint venture, to start service there now. Delta is growing fast in Boston and adding an Asia flight will help them solidify their position as Boston’s #1 global airline.”

“As a major gateway for high tech industries, Boston is the most popular unserved point from Korea with rapidly growing demand to Asia,” Jackson said. “The city, with its numerous universities and colleges, is a growing New England hub attracting companies in fast-growing industries like IT, bio-technology, healthcare, finance and pharmaceuticals.”

Massport Acting CEO John Pranckevicius said, “We welcome Korean Air to Boston Logan International Airport. This new nonstop flight to South Korea connects New England with one of the world’s largest economies in the globe. Korean Air’s commitment to fly 5 days a week to Boston also promotes tourism and bridges a gap in a growing global economy.”

The new Boston flight, along with Minneapolis/St. Paul-Seoul and Seattle-Osaka services that Delta is launching, are the first additions to the joint venture’s Transpacific network since the two carriers launched their partnership last May.

“By combining the schedules of Delta and Korean Air, our customers are able to enjoy unparalleled travel options,” Jackson said. “Our joint venture is undeniably the strongest Transpacific partnership and provides both of our airlines with a solid competitive edge.”

The Boston-Seoul service will operate five days a week on Korean Air’s new 787-9 Dreamliner aircraft with six First Class sleeper suites, 18 Prestige business class suites, and 245 seats in economy class.

First Class features farm-to-flight meals with food grown at the airline’s own farm on Jeju Island, a 23-inch high-resolution monitor, luxurious duvet and bedding and in-flight comfort clothing by Gianfranco Ferre. First class customers also can enjoy the exclusive benefits of a dedicated check-in lounge and First Class lounge at Incheon Airport.

Korean Air’s Prestige Suites offer private 21-inch wide flatbed seats spaced 75 inches apart with direct aisle access. Onboard, Prestige customers enjoy Korean Air’s award-wining food and wine program and a premium amenity kit.

Meanwhile, Korean Air’s economy class is among the industry’s most comfortable, with 33-34 inches between seats, a 10.6-inch high-resolution personal monitor and a variety of meal options.

The 787-9 Dreamliner is among the world’s most advanced aircraft with improved humidity and cabin pressure, dynamic lighting that can reduce jet lag, a state-of-the-art on-demand entertainment system, in-seat power, and large, electronically-dimmable cabin windows replacing traditional window shades.
