Sheer luck. I think there’s no particular logic behind the service, possibly just the availability of those mini-vans at certain times of the day. I initially thought it had to do (at least partially) with the number of connecting passengers travelling in business from certain routes (e.g. LHR) which tend to be busier than others, however on more than one occasion I was the only pax to benefit from the unpublished “perk” so, again, I would attempt a guess and say that it is merely all down to “transport availability”.

P.S.: HONs get the car transfer at WAW.
