Qantas is under fire from politicians and unions in Australia over plans to cut 1000 jobs and set up two new carriers in Asia.
Qantas also plans to mothball some of its older planes, defer new ones and shelve several long haul routes.
Union leaders are warning of the likelihood of industrial action.
Greens MP Adam Bandt the move offshore should be examined to see if it contravenes the intent of the Qantas Sale Act.
Labor Senator Glenn Sterle says Qantas' plans are the most frightening since Ansett Australia collapsed a decade ago.
Qantas chief executive Alan Joyce defends the changes, saying the company is building a better airline.
He denies there will be more job losses and says jobs are not being transferred offshore.
