The order, valued at nearly $300 million at current list prices, will become the airline's first direct-purchased airplanes from Boeing and fuel the airline's continued expansion within Asia's rapidly growing air travel market.
The order was previously attributed to an unidentified customer on Boeing's Orders & Deliveries website.
"This acquisition is a major step in our growth strategy," said Ken Choi, Chief Executive Officer, Jeju Air.
"We fully understand the benefits of owning and operating airplanes, which is what drove our decision to purchase these airplanes. We are confident that this order will enable Jeju Air to further strengthen our position as a leading low-cost carrier in Northeast Asia."
Jeju Air, based in South Korea was established as Korea's first low-cost carrier in 2005 and launched operations in 2006. The carrier currently serves 40 domestic and international routes with approximately 150 daily flights.
