I'm planning to fly back to Philippines at the start of September. Last week Skyscanner had Singapore Airlines for £480 to Manila with the "dodgy" travel sites and £500 actually with Singapore themselves. Also only £520 to Cebu from London. I thought I'd leave it a week to see about having the time off work, and now its up to £680.
I'm kicking myself. You can still get Malaysia for about £560 so I will probably have to choose them.
Omega travel still claims £511 with Singapore but I know that is crap
