Assuming my premise re use of little grey cells is correct one can only assume that the answer is "not many"!

Even if the answer is "quite a lot", I imagine the average yields are low. Warsaw is welded into the STAR network, so BA needs to offer attractive fares to encourage long-haul traffic through LHR.
LCC competition has trashed the yield/demand equation of the point to point traffic between Poland and the UK, so the weak contribution of connecting traffic is having to cover a fairish proportion of the operating costs, and justify the use of prime-time slots at LHR.
Not a happy picture for network carriers. We should expect further rationalisation of short-haul networks, and/or greater use of "partner" arlines/franchise arrangements.
