The revelation comes only a few days after the Treasury announced that it would guarantee the repayment of SA Airways' borrowings of up to R5-billion.

This lifeline has low-cost carriers seething.

The beleaguered national carrier has incurred losses amounting toR17-billion since the early 1990s.

A week ago it was hit by the resignation of seven of its board members, including chair Cheryl Carolus.

Comair CEO Erik Venter said that the losses being incurred by private carriers meant that they would not be able to operate. He said the lifeline given to SAA was driving low-cost airlines out of the market.

Venter claimed that SAA and government departments we re breaching the state' s own aviation transport policy.

He said nine of the 11 airlines that entered the domestic market since the early 1990s have crashed financially.

The latest casualty was Velvet Sky, which had its wings clipped in March.

Venter would not say that Comair would go so far as to institute court action, but said he wanted to see the government departments complying with aviation transport policy.

The airline industry has been hit by a 50% rise in the price of jet fuel in two years.

The domestic market is suffering from overcapacity - too many seats for too few passengers - a legacy of the optimism of 2010.

Passenger numbers are likely to dwindle further because of low economic growth.

Tariff increases of 70% imposed by the Airports Company of SA have also put immense pressure on the airlines.

The state-owned Acsa is one of 1time's biggest creditors.

1time CEO Blacky Komani said yesterday that his airline owed Acsa as much as R130-million.

Though 1time is not explicitly asking for a bailout, it does request "a reduction in the fuel levy and taxes to the aviation industry to reduce the significant cost of fuel".

Low-cost airlines operate on very thin profit margins and are extremely sensitive to increases in the fuel price.

In a delicately worded document addressed to the departments of transport, public enterprises and tourism, 1time's "business rescue practitioners" ask for "subsidisation".

Gerhard Holtzhauzen, CEO of Strategic Turnaround Solutions, claims a new approach would benefit not only 1time.

"Whilst this document wishes to address [sic] assistance package for 1time airline, it more importantly addresses a rescue package for the industry as a whole," Holtzhauzen wrote.

Apart from calling for a cut in the fuel levy, the document also suggests a reduction in statutory levies imposed by Acsa, Air Traffic Navigation Services, the SA Civil Aviation Authority and the SA Weather Service.

Holtzhauzen said both the Department of Transport and the Department of Public Enterprises could implement the requested subsidy scheme.

Minister of Public Enterprises Malusi Gigaba returned from Ghana yesterday morning and has, according to his spokesman, not seen the document.

But the Department of Transport has acknowledged receipt of the document, according to 1time's Komani.

Public Enterprises is the owner of SAA and its subsidiaries and can, therefore, get the national carrier to buy into the scheme and benefit from it, he said.

The Department of Transport represents the statutory bodies whose levies add to airlines' costs.
