Low-cost airline kulula has hit back at allegations that it is guilty of anti-competitive behaviour at Lanseria Airport, arguing that the accusations are "simply baseless".

Rival airline 1Time has reported kulula to the Competition Tribunal for allegedly robbing customers of choice by holding a five-year exclusivity deal with the privately-owned airfield.

The agreement was signed after kulula?s holding company Comair invested in infrastructure development at Lanseria.

The commission investigated the complaint and ruled that while the agreement was anti-competitive kulula has the right to recoup the money pumped into the airfield, adding it would not take the complaint further.

However, 1Time CEO Glenn Orsmond said he was taking it to the tribunal because kulula has inflated the numbers in terms of its investments.

?They?ve made no investment at Lanseria; I think they had to pay for one or two checking counters, which is about R30 000. I?d send them the money,? he said.

However, joint-CEO of Comair, Gidon Novick, said Comair needed to rake back millions.

?They [the Competition Commission] basically decided not to pursue it because that?s what businesses do, they take risks. Contrary to what Glenn says, we?ve invested about R100-million in the aircraft and the infrastructure,? he said.
