I see that when Qantas and Emirates join forces the new allowance for Y passengers on international flights will go up from 23kg to 30kg. I am off to Perth a few days after the new system kicks in and am wondering if the 30kg is just one piece. If it is I would not be able to lift it! I have called travel agent who said it is still one piece but then I rang Qantas and the customer service lady said she thinks it is two pieces totalling 30kg. The website just says 30 kg. Does anyone have better information before I start to pack? I don't want to get to Heathrow with two pieces and be penalised.
