Virgin Australia has applied to revoke its seat allocations on services to Greece and the Netherlands.
The request to Australia's International Air Services Commission (IASC) was made after restrictions on codesharing from Australia to the two countries were removed, says the carrier.
Prior to the application, Virgin Australia was allocated 400 and 800 seats per week to the Netherlands and Greece respectively.
The airline is also seeking to delay the implementation of its five times weekly codeshare with Singapore Airlines to Bangladesh until 24 March 2013.
This is because its application with the civil aviation authority of Bangladesh is still under consideration, adds Virgin Australia.
Separately, the IASC has allocated Qantas Airways 14 weekly services from Sydney and Melbourne to London with a Dubai stopover. This comes after the Australian flag carrier signed a partnership agreement with Emirates in September.
Qantas has the rights to operate services on these routes for five years and has to utilise the capacity by 31 October 2013, says the commission.
IASC has also awarded Delta Air Lines approval to codeshare with Virgin Australia on services from Australia to Indonesia. It has also permitted Singapore Airlines to codeshare with Virgin Australia on services from Australia to New Zealand, adds IASC.
