I have never flown Business to Australia only economy. There obviously wasnt enough room for the baby hence why i said buy him his own seat. Legroom on on Asian/Australia flights is bigger than European flight. Sinead is big but there are much bigger people flying . Not all big people can afford business class.You have to buy a seat for a two year old. Sinead didn't have to. If you read about taking an infant in business most places say there's enough room in your lie flat bed to make a little bed for them, thing is Sinead's size means that's not possible. Even less possible would be Sinead squeezed into an economy seat for that trek to Perth.
