Here is one for the suggestion box. Why not have a web tool that allows you to plug in your max price, a range of dates, and let the web site find available travel options for you? Say I have 2000-quid to spend in August, but no idea of where to go?
This LH tool does exactly that

But if I were BA, I would take this idea and make it work for CW and First class. Shouldn't management be keen on new revenue sources?
