India's Jet Airways announced on Monday that it will buy 75 more Boeing 737 Max planes as part of its efforts to launch routes and expand its market share in the country.
The Mumbai-headquartered airline said in a regulatory filing that it had entered another agreement with the US planemaker for the purchase of the aircraft.
A Jet Airways spokesman said the carrier had signed a similar order for 75 Boeing 737 Max aircraft in April.
It had also signed another order for 75 Max 8 planes in 2015, which means the airline now has a total of 225 Max series jets on order.
According to list prices of the 737 Max family, the latest order could be worth as much as $9.7bn. However, discounts in double-digit percentage are common for such orders.
The delivery of planes from the 2015 order were to begin by July, Indian media had previously reported.
Jet Airways, India's second largest airline, has a fleet of 119 aircraft flying on domestic and international routes.
India' civil aviation sector has seen massive expansion in the past years, with Indian carriers signing mega-deals with aircraft manufacturers.
Last year, Indian budget airline SpiceJet announced it would buy 205 planes, also from Boeing, in a deal pegged over $20bn.
