Budget carrier Tiger Airways' Australian division has been released from restrictions imposed by the country's civil aviation regulator.
Tiger Airways Australia had been flying on a conditional air operator's certificate following last year's high-profile grounding of the carrier over safety concerns.
In the wake of the July 2011 grounding - which followed incidents in which the carrier's aircraft had descend below minimum altitude levels - the carrier's operations were capped.
Tiger Airways Australia was permitted only to operate a limited number of sectors daily.
But the carrier's parent, Tiger Airways Holdings, says that Australia's Civil Aviation Safety Authority has issued the airline with a new air operator's certificate "without any restrictions" associated with the grounding.
"Over the last year we have worked hard to ensure that Tiger is second-to-none for safety, reliability and punctuality," says the airline's chief, Andrew David.
Tiger Airways Holdings adds that the carrier's safety management system has been improved and that the airline meets all of CASA's requirements.
