Getting away from Samoa

Does anyone know what options are there for travelling out of Samoa. I can find flights to NZ, and Oz, but what about direct to any other pacific islands?

Particularly Tonga, or Cook Islands?

Per week there is one flight to Tonga (Wednesday morning , Air NZ) and two flights to Fiji (Saturday and Tuesday early morning). That's all.

Just to add this: there is no flight between Tonga and the Cooks as well. So you will always have to go through Auckland to get to the Cooks.

Why not go downtown and talk to Polynesian Airlines?

There are plenty flights every day to Pago Pago

The OP did ask how to get on not how to get stuck ;-)

I might add that Fiji offers far more possiblities for onward travel than Tonga.
Alas, still no direct flight to the Cooks!
