It would seem that Iberia groundstaff can not really handle this and now we (and couple other CE-passengers) are waiting in a bus towards hotel (45min of trip) whereas two buses have already left. So, flying in Club with status doesn't really matter at outstations
BA contact center is naturally already closed so cannot do anything and the strike is announced as the cause of this cancellation.
I'll have to try the rerouting options but thenagain Im travelling with an infant so just the taxi ride to LHR is burden enough.
