Any good deals?

Now I've moved from the doorstep of Heathrow airport., more on the doorstep of East Midlands airport now. I'm having trouble trying to find a cheap flight for Harlene's Mum to come for a visit in the next couple of months.

Not even sure any airlines fly into East Midlands from Manila.

Don't really want to drive down to Heathrow, Birmingham could be a possibility. We've seen prices for Heathrow and Birmingham that go from £750-900.. is that the price now? Was hoping to get it for around £500-600
