How do I get to Popondeta
Since this is in the Aviation FAQ's I assume you want to know how to fly to PNP - Popondetta and not travel by ship.
Air Niugini flies daily to PNP and I believe that Airlines of PNG may have flights from Alotau (GUR) to PNP
It is probably best if you talk to a travel agent as they may know of other airlines flying to PNP. Also I suggest checking the www.airniugini.com.pg and apng.com web sites for online information.
