Air New Zealand has announced that it will double the number of Pacific premium economy seats available on its Boeing 777 fleet. Premium economy cabin seats will increase from 18 to 36, adding around 72,000 seats to the airline's Pacific flights every year. The first of eight planes will re-enter service this month, following a re-fit in Auckland. All of Air New Zealand's Boeing 777s will have been refurbished 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 has bases at Auckland, Wellington and other cities in New Zealand, and operates direct flights to destinations including Los Angeles, Sydney, and Hong Kong.
