Boeing and Singapore Airlines have announced an order for eight additional 777-300 Extended Range (ER) airplanes.

“This order is part of our ongoing fleet expansion and modernisation program, which enables us to offer our latest cabin products to our customers,” said Goh Choon Phong, chief executive officer for Singapore Airlines.

“The additional 777-300ERs will also help us further strengthen the Singapore Airlines network, providing our customers even more travel options.”

The Singapore Airlines order is valued at $2.4 billion at Boeing current list prices.

The order was first announced on August 10th, but Singapore Airlines had maintained its anonymity until now.

In total, Singapore Airlines has ordered 85 Boeing 777s, 27 of which are 777-300ERs.

“The men and women of Boeing are proud to build safe, comfortable and reliable airplanes for the passengers and crews of Singapore Airlines,” said Ray Conner, senior vice president of sales and customer support for Boeing Commercial Airplanes.

“For six generations, Boeing and SIA have together served Southeast Asia and the world with distinction.”

The Boeing 777-300ER is a favourite of passengers and airlines because of its ability to fly point-to-point and bypass crowded hub airports.

The 777-300ER is distinguished by its fuel efficiency, spacious cabin interior, range capability and commonality. SIA currently operates nearly every 777 model produced, including the 777-200, 777-200ER, 777-300 and 777-300ER.
