The airline is in the midst of a dramatic fleet revitalization, with the introduction of Airbus A350s and Boeing 787-10s and the launch of major new long-haul routes such as Singapore to Newark and Los Angeles, both of which took place within the last month or so. The airline is also in the midst of delivery of its order of new Airbus A380s, on which passengers will find its latest business-class seats and its much-lauded new first-class suites.
