Prime Minister Anthony Albanese is facing calls to launch a formal probe into flight upgrades he received as transport minister, as he lashed out at author Joe Aston, accusing him of failing to disclose his previous roles working for Liberal MPs, Qantas and his attendance at a Liberal fundraiser.

Mr Albanese on Tuesday sidestepped questions about claims in Aston’s book, The Chairman’s Lounge, that he would liaise with former Qantas boss Alan Joyce about his travel and received guaranteed flight upgrades.
