DUBAI: India’s Jet Airways confirmed on Monday an order for 75 Boeing 737 planes previously listed on the US manufacturer’s book as for an undisclosed client. It was the first big announcement at the Dubai Air show, which opened on Sunday amid low expectations for major sales. The Boeing 737 MAX 8 plane costs $110 million at list price. The carrier, partly owned by Etihad Airways, has a fleet of 115 aircraft.
