Why would 'type changes' necessitate a base closure anyway? Why would 'multiple type changes' be necessary? Why does the base have to close so quickly? Why can't some of the encumbents stay where they are and fly out of France but from a LON (CDG) base?
Surely the AOA lawyers could challenge this, delaying the process so that deadlines are missed. Concessions are more likely if the underprepared and under researched CX Basings Office is staring into a €30million abyss.
