There PLENTY of empty seats on my flight from Darwin to Melb. but I was squeezed in with 2 others. I eventually Moved to another row with only '1' person in it which allowed me to stretch my legs and move around a bit. Also I went with a friend and Expedia could have arranged it so I was sitting with my friend, instead we sat apart. On the Melb. to Darwin I asked if I could sit with my friend and it was Easy to arrange, why couldn't Expedia have done that.
