The Australian Competition and Consumer Commission said it was taking the action after Qantas “engaged in false, misleading or deceptive conduct by advertising tickets for more than 8,000 flights that it had already cancelled but not removed from sale”.

The commission said that in many cases, Qantas continued selling tickets or delayed telling ticket holders the flights had been cancelled. That often led customers to have less time to make alternative arrangements and to potentially pay higher prices for new flights, the commission said.

Qantas previously acknowledged its standards had fallen well short of expectations as the airline emerged from the Covid-19 pandemic.

Joyce said there was a lot he was proud about during his 22 years working for Qantas.

“In the last few weeks, the focus on Qantas and events of the past make it clear to me that the company needs to move ahead with its renewal as a priority,” he said in his statement.

“The best thing I can do under these circumstances is to bring forward my retirement and hand over to Vanessa and the new management team now, knowing they will do an excellent job.”

Last month Qantas announced a record pre-tax annual profit of nearly A$2.5 billion Australian dollars (US$1.6 billion), up from a loss of almost A$2 billion the previous year.

The airline has since come under pressure to pay back the A$2.7 billion it received from the Australian government during the pandemic.

Qantas Chairman Richard Goyder said the board thanked Joyce for his leadership.

“Alan has always had the best interests of Qantas front and centre, and today shows that,” Goyder said.
