To reach the snorkeling in American Samoa by air, you will need to fly into Pago Pago International Airport (PPG). There are two options. First, there is a twice a week flight from Honolulu on Hawaiian Airlines (five hours). Second, there are inter-island flights from Faleolo International Airport (APW) in Apia, Western Samoa, on Inter Island Airways (35 minutes). Faleolo International Airport has numerous international flights from New Zealand, Fiji, Tahiti, Hawaii and Los Angeles. To reach the other islands of American Samoa, Inter Island Airways also flies from Pago Pago International Airport to Tutuila Island and to Manu Island. Alternately, the American Samoa Port Administration operates a bi-weekly ferry service between Pago Pago, Tutuila and the Manu'a Islands aboard the MV Sili. A good base is the funky Apia Town.
TIP: Keep in mind that there was a significant tsunami in 2009 that damaged American Samoa. These large events tend to damage the shallow water reef formations; there are reports that the coral is slowly starting to regenerate in the waters off American Samoa. Also, this is a very tropical island with plenty of swarming mosquitos, so make sure to bring bug spray and a mosquito net for sleeping.
