Boeing has secured a $300m order for three next-generation 737-800 aircraft from South Korean low-cost carrier Jeju Air.

With the new order, Jeju Air aims to continue to expand its presence across Asia.

The airline currently has an all-Boeing fleet of 26 next-generation 737-800 planes, and serves 40 domestic and international routes.

"The 737 forms the backbone of our fleet and it has been a reliable workhorse for our airline over the past decade."

Jeju Air CEO Ken Choi said: "This acquisition is a major step in our growth strategy.

"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 North-East Asia.

"In addition, the 737 forms the backbone of our fleet and it has been a reliable workhorse for our airline over the past decade.”

The new 737-800s will be equipped with Boeing Sky Interior, decorative sculpted sidewalls, larger window reveals, LED mood lighting, larger pivot overhead stowage bins, and other specifications.

Earlier this month, Boeing secured a $550m order for five 737 8 MAX aircraft from Czech airline Travel Service.

In 2013, Travel Service ordered three 737 MAX aircraft and currently operates a mixed fleet that includes 32 737 planes from Boeing.
