Judging from
this, it looks as if the best route today and tomorrow is to start from GLA, PIK or BFS, and then route via N55/W25 to N40/W25.
From there, the Midi and the Med are your oyster.
Makes that old French-ATC-Strike routing (via 8 West) look comparitively direct!
Quite how you get to the departure airfield is another (expensive?) matter...
