Indonesia's Lion Air is buying 50 Boeing 737 MAX 10 airplanes in a deal valued at about $6.2 billion, the firms said Tuesday, as the carrier looks to cash in on a transport boom in the Southeast Asian nation.

The new single-aisle plane is the latest incarnation of Boeing's 737 MAX series, which can accommodate between 130 and 230 passengers and fly up to 3,850 nautical miles (7,130 kilometres).
