Boeing and Korean Air finalized the airline's order of 30 737 MAXs and two additional 777-300ER (Extended Range) jetliners valued at nearly $4 billion at current list prices. The airline also has options for additional 737 MAXs as part of the order, which was previously announced as a commitment during the Paris Air Show in June.

With this order for up to 52 Boeing airplanes, Korean Air becomes Boeing's newest 737 MAX customer and now has 62 firm Boeing airplane orders on backlog.

Korean Air currently operates a fleet of 91 Boeing passenger airplanes that consist of 737, 747 and 777 airplanes. The airline also operates an all-Boeing cargo fleet of 28 747-400, 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 distinctive raked wing-tips for each model. They are also one of two suppliers producing the new 737 MAX Advanced Technology (AT) Winglet.
