Pago Pago International Airport

Pago Pago International Airport carries the IATA code PPG — the three letters printed on boarding passes and baggage tags — and the ICAO code NSTU, used in flight plans and by air traffic control. It serves Pago Pago, American Samoa.

IATA codes are assigned by the International Air Transport Association for passenger-facing use; the four-letter ICAO code encodes region and country and belongs to the operational side of aviation.
