Not sure if you have Qatar Air in and out of Bangkok, but I had to go to the UK 4 weeks before Christmas for my Mums Funeral. I got a return from Perth to London for just under $1500AUD which was pretty good compared to what others wanted so close to Xmas.
Flew Perth to Dhoa in just over 11hrs, 2 hr layover in Dhoa and then just over 7 hours to London. My 1st time using them, and was pretty impressed with the overall service.
Have a look and see how they compare to Emirates, it might be worth a look
