So this to me seems to be the reason the BA723 was cancelled - the plane not being there! No GVA airspace restrictions in the morning as plenty of flight arriving and departing. The flight after ours to LHR was cancelled too, the BA727.
There was something oif a mini meltdown at LHR on the afternoon of 30 June, see the dedicated thread for that, so I think you would have been caught in that. You can either take the matter to CEDR if you get confirmation from BA that they won't change their position, or you can go MCOL. In the case of CEDR, BA has to prove their case, MCOL is more balanced in that respect, but I can't see BA defending a 250€ claim if they are up against plausible arguments.
