I never sleep on the way over there but on the way home I have been given three seats to myself And so I pull up the arm rests and make myself cosy with pillows and blankets. I manage to get 3-4 hours in.
Oh and btw quickerblade, V Australia is so much better than Quantas.
I have been on both, i like Qantas cause i have heaps of points and get to travel business class.V Australia is cool too.
