Virgin Australia says it will provide additional capacity to minimise the impact of ongoing Qantas industrial action on the Australian travel and tourism industry.

"Over the last three months, we have increased our capacity around Australia, adding more than 31,000 seats each week, including expanding our presence in the very important Perth market, where we have introduced wide-body aircraft and business class seats," Virgin Australia group of airlines chief executive John Borghetti said.

Mr Borghetti said 6,800 seats had been added to its Perth routes, with business class available on all flights from the East Coast.

"In addition to this, we have already put plans in place to add extra capacity over the next few weeks," Mr Borghetti said in a statement on Wednesday.

This includes 3,000 additional seats each week up to October 30 and the addition of a fifth daily return service from Melbourne to Perth commencing December 20, adding a further 2,300 seats each week.

"We are well advanced in discussions with alliance partners Etihad Airways and Air New Zealand on providing extra capacity from November, leading into the busy December and January holiday period," Mr Borghetti said.

"We will continue to work with all of our alliance partners who are keen to help us support the Australian travelling public and ensure tourism is not affected, both domestically and internationally."

Virgin said that with all its alliances in place, Virgin Australia's global network capacity share in and out of Australia was forecast to be around equal to that of the oneworld airline alliance in 2012.

Qantas, but not Virgin, is the Australian member of the 12-airline oneworld alliance.

Mr Borghetti said the airline group would be closely monitoring the Queensland market to ensure it could meet any additional capacity needs as that important tourism market rebuilds after the devastating floods and cyclones.
