Just put the dates for 25th of november until 17th december and the cheapest now is emirates at £530 then Cathay now at £596.

Can be such a headache booking flights, its not always just the price but the times leaving london for me, and then leaving manila.

I paid £475 to travel in September with Cathay which was a special offer, because i missed my flight back to London, I then had to pay £550 just one way back home. I was sick by the way so hopefully the travel insurance will pick up most of that.
Flights do seem slightly cheaper right now than in March. I paid over £600 with Ethiad at that time. But it's how long you can hang on for a good price before you really need to book
