Korean Air announced the airline’s intent to purchase up to fifty A321neo aircraft including thirty firm orders and twenty options along with 30 B737 MAXs and two additional B777-300ER aircraft with options for an additional 20 B737 MAXs.

“This agreement reflects Korean Air’s ongoing fleet modernisation programme and we are committed to introducing new next-generation aircraft that are environmentally friendly and fuel efficient, while also providing maximum comfort to our passengers,” said Walter Cho, executive VP and chief marketing officer, Korean Air.

With this commitment Korean Air is poised to become a new B737 MAX customer when this order, which includes MAX 8s and substitution rights for MAX 9s, is finalised. With this commitment, the Korean flag carrier will increase the size of its unfilled orders with Boeing to 69 aircraft.

This most recent agreement comes on the heels of the airline’s order for five B777 Freighters earlier this year, raising Korean Air’s total orders and commitments with Boeing in the first six months of 2015 to 37 aircraft. Korean Air currently operates a fleet of 87 Boeing passenger aircraft that consist of B737, B747 and B777s.

The airline also operates an all-Boeing cargo fleet of 27 B747-400, B747-8 and B777 Freighters.
