Singapore Airlines (SIA) said Wednesday it has placed an order for eight more Boeing 777-300ER aircraft worth US$2.3 billion at list prices.

The order is to support the Singapore carrier's growth plans, SIA said in a statement.

These additional B777-300ERs will help support our ongoing programme to further strengthen the Singapore Airlines network, providing more travel options to our customers, chief executive Goh Choon Phong said.

The order is in line with our longstanding policy of operating a young and modern fleet.

Goh said the fresh orders will enable the carrier to offer our latest cabin products which have proven extremely popular with our customers.

SIA's current 106-strong fleet includes 19 Boeing 777-300ERs, the carrier said.
