Pago Pago International Airport (PPG) on Tutuila is the only point of entry for most visitors. It's not well-connected — getting here requires planning.
From Hawaii: Hawaiian Airlines flies between Honolulu and Pago Pago. This is the main link to the US mainland and typically the most reliable option.
From Samoa (independent): Samoa Airways and Talofa Airways both operate frequent flights between Apia (Faleolo Airport) and Pago Pago. The crossing is about 45 minutes and there are often daily services. The Samoa Shipping Corporation also runs a weekly ferry between Apia and Pago Pago — a slower but scenic option.
From Fiji and Tonga: Talofa Airways flies from Tonga, and there are connections through Apia from Fiji. Pacific flying generally requires island-hopping; don't expect direct routes from most places.
To the Manu'a Islands: Samoa Airways operates small-plane flights from Pago Pago to Ofu and Ta'u. Flights are infrequent — check schedules carefully and book ahead. Weather cancellations are common. There is also an inter-island ferry service, but it runs infrequently and can be rough.
Getting to American Samoa takes effort. Build buffer time into your itinerary, especially for onward travel to the outer islands.
