I have just booked with Cathay to Manila for £475.
Flying on September 4th. Booked with Netflights, the other sites claimed cheaper but i know not to waste time calling them. I'm very happy as its the cheapest i've paid for years.
The only problem is i like to leave London in the morning to get to Philippines early afternoon next day and leave Manila late eveningvon return. All of these flights leave london in the evening and leave manila very early in the morning. So not perfect
