The American Samoa governor, Togiola Tulafono, is supporting a request by Polynesian Airlines to the US Department of Transportation to allow it to continue flying the territory's Manu'a route.
Polynesia Airlines wants an exemption to the federal cabotage rule which prohibits any international carriers flying US domestic routes.
The territory's sole airline, Samoa Air, has been unable to operate since its only plane was put into maintenance in September..
But there has been reportedly no work carried out on the plane and Polynesia has now requested an extension to continue flying for the crippled airline.
Mr Tulafono says he has urged the Department of Transportation to approve the extension.
A decision is expected tomorrow.
