Jetstar is willing to come to the table with pilots after they walked off the job - but not at any cost.
Negotiations between the airline and union officials have broken down, causing flight disruptions nationwide after some downed controls on Saturday.
"This situation is very, very sad. We absolutely want to do a deal that rewards our people for the great work that they do every day but we're not going to do that at any cost," Jetstar chief executive Gareth Evans told reporters in Melbourne on Saturday.
It is not clear how many pilots had walked off the job over the weekend, the executive said.
The airline cancelled 44 services on Saturday and 26 on Sunday because of the action.
Pay talks broke down after nearly a year, with Jetstar warning it wasn't prepared to alter its position.
The airline claims the union's demands would lead to a 15 per cent net wage increase, which would cause fares to go up.
However the Australian Federation of Air Pilots claims they want a three per cent raise for pilots and the other figure is based on "inaccurate" costings of other conditions.
"If they've accepted the three per cent pay rise that's fantastic; let's call off the action and get back around the table," Mr Evans said.
"But the fact they're taking action would suggest what they've got on the table is much more than that."
Jetstar wants a resolution but will only consider one when the stoppage is called off, he said.
Lower level bans will start on Saturday and end on December 20 but flights from that date until January 3 will not be impacted.
"We have realistically been left with no alternative but to take this action. It is not something we take lightly," union executive director Simon Lutton said on Saturday morning.
Passengers are being told they will be notified if their flight is disrupted, as long as their contact details are up to date.
Those affected will be able to change flights or get a refund.
