Towards liquidation
The airline stopped selling international flights on 23 April 2004, and announced that the last international flight would leave Tongatapu for Auckland the following day, whereby the Boeing 757 was repossessed for non-payment and returned to Royal Brunei Airlines. Whilst airline management provided no reasons for the cessation of international flights, it was believed to be linked to the funding crisis which was being experienced by the state-owned airline.[23][24] After the closure, Tonga was reliant on Air New Zealand, Air Pacific, Air Fiji and Polynesian Airlines for international air services.[25] The cessation of international flights also had the side effect of stranding mail being sent to Tonga in Auckland, up to a month afterwards, due to limited cargo space being available on the Air New Zealand flights to the nation, and in late May it was reported that the nation had not received mail for a week.[26]
Akilisi Pohiva, a pro-democracy member of Tonga's parliament blamed King Taufa'ahau Tupou IV for the financial crisis of the airline, and called on the king to use his own funds to bail Royal Tongan out of its financial woes.[27] He noted that the Tupou had issued a royal decree for the 757 project to proceed, despite opposition from the cabinet and parliament, and claimed that the monarchy is not accountable to the public.[28]
On 18 May 2004, the airline ceased all operations with the remaining one hundred employees losing their jobs, and the islands of Tonga being left without domestic air service. The closure was forced as the airline's only airworthy aircraft, the Shorts 360, broke down and the airline had no funds with which to repair it. Airline administration was hoping that the government would bail it out, but this did not eventuate.[29]
In discussing the sending of Australian and New Zealand specialists to Tonga, to help the government wind up the airline, Phil Goff, the New Zealand Minister of Foreign Affairs stated "lessons can be learned from how and why the RTA collapsed."[30] The Tongan government confirmed that it had a financial commitment in the airline to the value of 14 million Tongan paʻanga, and had pumped some 20 million paʻanga into the airline since its inception in 1985.[30]
In July 2004 PricewaterhouseCoopers found that the only substantial remaining assets of the company were a hangar and the two aircraft. It recommended that the aircraft be repaired and sold.[31] By December 2004, it was reported that creditors had lodged claims of US$8.5 million from the liquidators, but had recovered only US$1.13 million from the sale of assets. PricewaterCoopers also noted that only 106 of 206 former employees of the airline had thus far lodged claims.[32] The Twin Otter was sold in January 2005 for US$850,000, and the sale of assets from the airline's offices in Nukuʻalofa and abroad netted US$71,000 and US$8,000 respectively.[33]
In the absence of domestic flights in Tonga, by June 2004 Air Waves of Vava'u and Fly Niu Airlines had begun operations on some of the former Royal Tongan routes.[34]
