The International Air Services Commission (IASC) has granted a one-year extension for the proposed codeshare agreement between Qantas and South African Airways.
The codeshare agreement will be valid until 31 December 2012.
In its response, SAA said while it welcomed the one-year approval, the small-time period could make it extremely difficult for the airline to plan its ongoing medium and long-term strategies on the Australia-South Africa routes.
In its statement, Qantas said the decision raised questions about the future direction of government policy and criteria used by the IASC to assess public benefit.
Meanwhile, Qantas has sought IASC permission to operate unlimited capacity between points in Australia and points in Japan, other than Narita and Haneda airports, for a period of 10 years.
The airline's application says the capacity may be used by any airline that is part of the Qantas group or to provide joint services with airlines in the Qantas group.
