The Veronicas say Qantas flight attendant hid his ID amid baggage row

Pop duo The Veronicas have accused a Qantas flight attendant of obstructing his ID card, days after they were removed from a flight at the weekend.

Sisters Jessica and Lisa Origliasso threatened legal action against the airline after being asked to leave a plane bound from Sydney to Brisbane on Sunday morning.

On Friday, the pair posted on social media alleging a flight attendant obscured his Aviation Security Identification Card after threatening to call security.

The dispute over cabin baggage saw Australian Federal Police come on board the flight.

They claim the man "turned his body away so we could not see his badge" upon telling them he was going to call security.

When he returned he had his ID card pinned backwards, the pair claimed in a social media post with accompanying photo.

Earlier this week Qantas said two passengers refused to follow the cabin crew's instructions and were "offloaded" before the flight took off.

The AFP said officers came on board amid an argument between the two passengers and staff before the women agreed to disembark, with no further issues.

Qantas has been approached for a response to the latest claims.
