I've been looking for alternative routes too especially from Birmingham. I did see flights to Hong Kong for just over £400 with Turkish Airlines a while back but was put off by their safety record.
Also, last week I saw flights with Finnair going to Hong Kong from Birmingham for under £500 changing planes in Helsinki. Not a bad price from Birmingham especially if you can get a promo flight from HK to Phils. I could have done just that but connection times were too long coming back. Plumped for Kuwait Airways at £528 in the end, Heathrow to NAIA, 20/22 hours travel time. Could have got it for £20 less a day earlier too but I messed around looking for other deals and missed out.
Anyone know why Saudi's flights are ridiculously high now? Went to Phils for £444 in 2011 now they're about £800.
