Jet Airways on Tuesday said it will buy 10 aircraft from US-based aerospace major Boeing to expand its international operations.

The company informed the Bombay Stock Exchange it has signed an agreement with US-based The Boeing Company for acquisition of 10 Boeing 787-8 series aircraft, subject to regulatory approvals.

Boeing would deliver the aircraft between July 2011 and December 2012. The company did not disclose the financial details of the agreement.

However, sources said the deal could be valued at about $1.5-2 billion. Under the agreement, Jet has the option to substitute other models of Boeing aircraft. Meanwhile, Jet would take delivery of the B777-300 ER and A330-200 aircraft, ordered in September and October 2005 respectively, during March-April 2007.

Meanwhile, Jet Airways executive director Saroj Dutta told PTI the company would decide on utilising the aircraft on various international routes only when the time for taking deliveries approaches.

"We will be getting the first plane by June-July 2011, by when, our international operations will mature. We will finalise plans to using these aircraft on international routes only then," he said.

The acquisition of larger wide-bodied aircraft such as the Boeing 787 series would help the company expand its overseas operations, he said.

Dutta said Jet would also take delivery of the Boeing B777-300ER and Airbus A330-200 aircraft in March-April this year.
