Melbourne to London flights

 - Don't Have a look at Royal BrownEye 
 - Royal Brunei are about the cheapest. Bear in mind you have two stops and they don't serve alcohol (you can BYO though). We're using them in June/July and saving about $500 for the four of us. I'm not a huge fan of them as they have stuffed my vegetarian meals up, not clean and the stopovers suck but you get what you pay for! 
 - A trick I picked up is if you can get yourself to Colombo from Melbourne, say on Air Asia etc, a return flight Colombo-London on Qatar business class costs less than $1500. The only way I'll be able to afford business class! 
 - Thai Airways is coming up as $1429 on SkyScanner if you leave on 31 August… - http://www.skyscanner.com.au/transport/flights/mel/lond/1608… 
 - Now you can fly return for $938 if you are willing to depart on 27 September… 

Have a look at Royal Brunei
