Qantas domestic passengers will soon be able to board flights with heavier carry-on bags after travellers complained about the airline's 7-kilogram limit.
From March 25, travellers will be allowed to carry on one item weighing as much as 10 kilograms and a second piece up to 4 kilograms.
Currently, travellers are allowed to bring two carry-on bags weighing no more than 7kg per piece.
The total cabin baggage weight limit will still be 14 kilograms per person, with the rule change allowing one bag to be heavier than the other.
The physical size limits on cabin bags remain the same.
Passengers are also still allowed to bring one small personal item bag, such as a handbag or slim laptop bag, as well as the two carry-on bags.
Qantas said airline crews will be at the airport to ensure passengers are adhering to the new baggage policy, adding that any piece of cabin baggage weighing more than 10 kilograms will have to be checked in.
The decision followed a trial over summer which included weighing passengers' carry-on bags at the boarding gate.
It found that while nine out of 10 travellers had less than 10 kilograms of cabin baggage in total, about 40 per cent of passengers had bags weighing between 7 and 10 kilograms.
"We’ve had feedback from our frequent flyers who said they can easily keep within the 14 kilogram limit but would like flexibility in how they use their cabin baggage allowance," Qantas Domestic chief executive Andrew David said.
But the perks of the change aren't just for passengers.
The airline hopes the new policy will see passengers boarding with 10 kilograms in a single cabin-bag rather than split their load across into two bags, which will free up space in the aircraft's overhead luggage bins.
Heavy bags or overhead baggage compartments that are too full can cause a safety risk for customers and crew, Mr David said.
