Tata-owned Air India is close to signing a deal with Boeing to acquire up to 150 737 Max jets, said people with knowledge of the matter. The order will be Air India’s first major aircraft order after its privatisation. This will be Boeing’s first big sale deal in India after it won a mandate for 75 aircraft from Akasa Air last year. India’s narrow body fleet is dominated by the Airbus A320. Air India will likely place a firm order for 50 737 Max planes with an option to pick up as many as 150, said the people cited above.
