It will also be extra efficient, extra environmentally friendly and quiet, as it will feature all the advanced technologies available in the first part of the 21st Century, bringing the A380 experience to a new level.The all-new A350 XWB will offer Singapore Airlines unrivalled operating performance and economics, whilst passengers will enjoy outstanding comfort and amenities in a highly advanced and spacious cabin environment."We are very proud to have Singapore Airlines as a very early customer for the all new A350 XWB, particularly since it follows the announcement for nine additional A380 orders and 19 A330 leases. As one of the undisputed leaders of the global air transport industry, Singapore Airlines sets the most demanding standards to ensure that its aircraft combine outstanding passenger appeal, unbeatable efficiency and exceptional environmental friendliness.
