Where are the cheap flights

China Airlines, never again.
Try Turkish Airlines - my friend uses them a lot.

I think Turkish Airlines have one of the worst safety records.

Asiana Airlines £527
Malaysian Airlines £529
KLM £558

Just a few fares I saw for November going from LHR to MNL.

Asiana and KLM both have one of the journeys at around 40 hours, hence the price I'd imagine.
