Air Niugini MD Alan Milne said the new facility was the airline's flagship.
"This is our newest and biggest domestic sales facility. It is also close to bus stops and is a ‘one stop shop' where customers can do their shopping and other business in the same area."
The new sales office has been in operation for the last two weeks, from 8am to 5pm. But from this weekend the operating hours were extended from 8am to 8pm.
"The office currently has 15 staff members but this is expected to increase to more than 20 with several domestic and international counters in the retail section and corporate sales. This will serve the increasing number of customers and corporate clients including group travel, VIP and government travel," Air Niugini said.
