SEOUL, Nov 20 (Reuters) - Jeju Air Co Ltd, South Korea's biggest low-cost carrier, purchased 40 Boeing 737 Max 8 planes worth $4.4 billion, the airline said on Tuesday.
The deal marks the biggest contract by a South Korean carrier in numbers of a single aircraft type model, the company said.
Reuters exclusively reported earlier this month that Jeju Air was in talks with Boeing and Airbus to buy 50 jets as the airline planned to expand its network that includes one of the world's busiest routes.
The purchase contract includes an option to buy an additional 10 aircraft, Jeju Air said.
The airline operator said it planned to take delivery of the planes between 2022 and 2026.
Six South Korean budget carriers saw the number of passengers using international routes quadruple to 20.3 million in 2017 from 4.9 million in 2013, according to South Korea's transport ministry.
"The order of Boeing 737 Max planes will help the company maintain its cost competitiveness, fuelling us to grow as a leading carrier," Jeju Air said.
The company currently operates 58 routes with 38 Boeing 737-700 planes. (Reporting by Heekyong Yang; Editing by Amrutha Gayathri and Sherry Jacob-Phillips)
