That will change soon, as a $40 million project will begin in December to extend the runway an additional 345 meters (1132 feet), which will allow unrestricted use by aircraft such as the 737-800s which Air Pacific presently flies between Hawaii and Nadi. (But still not the "heavy iron" like 747s or MD-11s).
Above: View on final approach to runway 10 at Nausori Airport (Suva International) in an Air Fiji Embraer EMB-120 Brasilia (a twin engine turbo prop). The plane is headed approximately East with the Rewa River on the right.
The newly completed bridge over the Rewa River that you may have read about on Babasiga already makes it easier to get to the airport. By the way, NZM of M and J Adventures tells me that her first ever airplane ride was from this airport - in a DC-3. I would add on her behalf that the DC - 3 does not indicate NZM's age, but rather the slower pace of aviation progress in Fiji.
In addition, a new terminal building will be constructed starting in May of next year. The improvements will make a big difference to Suva bound travelers. This is good news for me too, as Nausori is much closer to Taveuni than is Nadi and will shave an hour off regional trips.
