Real Tonga Airlines is hoping to use the government's controversial MA60 aircraft on services to Fiji and Samoa.
The airline recently won the bid to operate the MA60 after a previous lease between the two was terminated in February after the 56-seater plane was grounded.
Real Tonga's chief executive Tevita Palu says the company is now waiting on the government to certify the aircraft but he hopes to use it for international routes.
"There is nothing stopping us from doing that. The aeroplane, the MA60, it was not capable of doing that route before so hopefully this time round the aircraft will be certified to serve those routes."
Tevita Palu says he should find out about the certification within a couple of weeks.
Last month Real Tonga started a Fiji-Tongatapu-Vava'u route with a Fiji Airways plane as part of a short-term arrangement.
