What flight comparison websites do people recommend? Up until a year or so ago, the only one I knew of was expedia. But there seem to be so many now - I know of Kayak, Holiday Hypermarket, Cheap Holiday Deals and Skyscanner, and there are probably loads of other ones too. I've found that sometimes they do come up with different prices but haven't noticed any consistent patterns in terms of one being cheaper than another. Is there a particular one that anyone would recommend?
