In 2011, Air New Zealand introduced the Boeing 777-300ER airliner, as well as the Economy Skycouch, a set of three economy class seats that could be converted into a flat multi-purpose surface by raising the leg rests. After a four-year delay, Air New Zealand took delivery of its first Boeing 787-9 on 9 July 2014. The airline retired its last Boeing 747 in September 2014, the last Boeing 737 in September 2015, and the last Boeing 767 in March 2017, leaving it with a simplified fleet of Airbus A320 aircraft for short-haul and Boeing 777 and 787 aircraft for long-haul.
