The update I was given based on the slot information is below. I guess the start date plus any of the stuff below could easily change. On top of the health warning that this can and probably will change, this only covers flying at slot constrained UK airports so omits plans to fly between airports that aren't slot restricted. So if BHD-LPL, BHD-CWL etc etc are in the plan, they won't be listed here.
