is not a duplicate of:
(I was one of five who voted to close on that basis.)
Transfer between two major airports serving the same city arises not only for Paris and since of relevance to many travellers might perhaps justify being considered a 'special case'.
However the underlying issue is that to escape ORY (even to a different terminal at the same airport) Immigration must be crossed. Landside requires a Schengen visa (for those requiring a visa) and hence the destination is of no relevance for the issue.
Is two different specific destinations enough to rule out deemed 'duplication' or is ORY>CDG a special (not necessarily unique) case?
Does an Indian need a visa to transfer from Paris ORY to Paris LBG?
Does an Indian need a visa to transfer from Paris ORY to 8 Place de la Concorde, Paris?
Does an Indian need a visa to transfer from Paris ORY to 6 Place de la Concorde, Paris?
There is a lot about what does/does not/should constitutes a duplicate here but my question is restricted to consideration only of destinations for visa purposes and assumes an answer (to at least one of the Qs) of a general nature, such as @Relaxed's, which includes a section:
Can you transfer without leaving the international area of the airport?
(Where, for example, specific nationality is not relevant either.)
