Lufthansa start their autumn worldwide sale on Wednesday.
Although they don't fly to Manila, they do fly to Singapore, Hong Kong and Bangkok as well as many other Asian cities.
They also fly from regional airports in the UK to their hubs in Frankfurt and Munich for the onward destination, and like KLM they usually have one of the shortest total travelling times to the Far East.
For best prices, book direct at their website.
In their last sale I managed to get a Birmingham to Singapore flight for £430 inc all fees and taxes
I'm hoping I can pick up another bargain to somewhere on Weds
