The deal was completed in 2012 and follows an agreement in October 2012. Singapore will use the A350-900s on medium- and long-haul routes.
Singapore Airlines is the second largest commercial operator of the A380, and has 19 aircraft in service. In the mid-size category, the new A350 XWB order sees the airline double its backlog for the all-new aircraft to 40.
Since first entering service with Singapore Airlines in 2007, the A380 has joined the fleets of nine world class carriers. Typically seating 525 passengers in three classes, the aircraft can fly as far as 8,500 nautical miles non-stop.
The A350 XWB (Xtra Wide-Body) is a mid-size long-range passenger jet with three versions and seating between 270 and 350 passengers. Entry into service is scheduled for 2014.
