As per the title. Mrs RC says "you have lots of avios, let's do a long cheap family weekend somewhere over the august bank holiday weekend".

I say.... well, let's just say that words fail me. 4 return avios flights anywhere at all over that weekend? Hmm. So having checked a few of the usual suspects and got nowhere, is there an easier way... any search engine that will let me plug in the dates and number of seats needed and just tell me if there is anywhere in the world (ideally Europe) that has availability? Because I think the answer could well be 'no'
