Virgin is also expected to announce changes to cabin products on Wednesday after several announcements of more transtasman flying following a bust up with current partner Air New Zealand.
The two airlines will go their separate ways from October 28 following a seven-year commercial alliance in what is becoming a rancorous divorce.
Virgin Australia has announced new flights between Newcastle and Auckland, Melbourne and Queenstown, and Sydney and Wellington as well as increased services between Auckland and major Australian cities.

Air New Zealand will also fly more transtasman services and, after October 28, will code share with Virgin's rival, Qantas, in domestic markets in this country and across the Tasman.
Virgin says it teamed up with the White Lady because the 70-year-old burger joint was such an established Kiwi institution.
The White Lady was founded by Bryan (Pop) Washer — seven years before McDonalds — to cater for the 6 o'clock swill market initially selling ''pea, pie and pud'' before moving into burgers in the 1960s.
Washer's son Peter and grandson Max now run the business from two outlets in downtown Auckland, including the traditional pie cart parked up 365 nights a year.
Max Washer said the business had operated without a break for 70 years and on the weekends was open around the clock.
Five staff would serve up its King Burger (melted cheese, beef, onions, a fried egg and lettuce) between 12 noon and 2pm. He said staff had plenty of experience at mass catering, serving up to 6000 burgers during a busy week.
''We've got pretty good systems,'' said Washer.
