General Manager Dominic Kaumu revealed this yesterday after its first commercial flight to Bauerfield International Airport in Vanuatu, Port Vila.
He said the inaugural flight will include very important people including Prime Minister Peter O'Neill and other government ministers and officers.
Kaumu said the commercial flight today signifies a strong relationship Papua New Guinea has with the other Melanesian Spearhead Group countries.
So far Air Niugini is servicing three MSG countries.
These are Solomon Island, Fiji and now Vanuatu.
Kaumu said Air Niugini will be increasing its flights to Port Vila in the near future.
Currently they will only do one weekly flight to Port Vila via Honiara.
