PARIS AIR SHOW, Boeing (NYSE: BA) and Korean Air today announced that the airline has agreed to purchase five 747-8 intercontinental and six 777-300ER (Extended Range) aircraft, valued at about $3.6 billion at current list prices.

Boeing will work with Korean Air to finalize the order.

Ray Conner Boeing Commercial Airplanes' President and chief executive officer, said: "Korean Air is a valued Boeing customer and their commitment to add more Boeing twin-aisle airplanes to their fleet demonstrates our strong partnership.

"Korean Air has steadily built its reputation as an early adopter of new technology and innovation and Boeing airplanes have played an instrumental role in that strategy.

"Boeing shares a unique relationship with Korean Air—both as a customer and a supplier for Boeing.

"Our partnership is built upon trust and is multifaceted, which brings us closer on many levels."

Korean Air is the only airline to order both the passenger and freighter variations of the 747-8.  Once today's order is finalized, Korea's flag carrier will have ten Boeing 747-8 Intercontinental aircraft on order. The airline has taken delivery of three of its seven Boeing 747-8 Freighters on order.

Korean Air operates a fleet of 90 Boeing passenger airplanes that consist of 737, 747 and 777 aircraft. The airline also operates an all-Boeing cargo fleet of 27 747-400, 747-8 and 777 Freighters. In February 2012, Korean Air became the first airline to operate both the 747-8 and 777 Freighters.

Korean Air's Aerospace Division is a key Boeing partner on both the 747-8 and 787 programs, supplying the raked wing-tips for each model.
