Air New Zealand has announced that it will double the number of Pacific premium economy seats available on its Boeing 777 fleet. Premium economy spaces will increase from 18 to 36 on each aircraft, adding in the region of 72,000 seats to Air New Zealand's Pacific flight passenger capacity every year. The first of eight refurbished planes will re-enter service this month, with all of Air New Zealand's Boeing 777s receiving the new layout by mid-June. Air New Zealand's general manager for long-haul services, Ed Sims, said: 'Pacific premium economy has been hugely popular since its introduction in 2005. 'Air New Zealand flies further than any other airline in the world. Despite the challenging economic environment, long-haul customers clearly value the experience and are happy to pay more for the superior legroom, personal space and business class-style service. ' Air New Zealand operates direct flights to Los Angeles, Sydney, Hong Kong and other destinations from its bases at Auckland, Wellington and other cities in New Zealand.
