The positive case is a local resident who arrived back in American Samoa last week on a flight from Honolulu.
American Samoa's quarantine facility for incoming travellers from Samoa and Tonga has been closed so that the positive COVID-19 case can be isolated.
Lieutenant Governor, Talauega Eleasalo Ale said the flight suspension is temporary while the government works on a facility to quarantine travellers from Samoa and Tonga.
