Saudi Arabia's Public Investment Fund (PIF) is close to a deal for Boeing Co. commercial jets for the fleet of a new national airline, the Wall Street Journal reported on Saturday, citing people familiar with the matter.

The aircraft order is valued at $35 billion, the report said, adding that the deal could be announced as soon as Sunday during an official launch of the national airline.

The deal includes wide body jets which are often used for long international flights, the report added.

Boeing declined to comment while the Saudi PIF did not immediately respond to a request from Reuters for comment on the report.

The deal is part of a rapid expansion by the country under a strategy to transform the kingdom into a transport hub and promote tourism.
