I was trying to interline a bag from AF to DL in DUB on separate reservations. The staff at the CDG 2E business check-in wouldn't interline across reservations and a supervisor confirmed it.
They said it's a long-standing policy ("2 years") but my experience has been different, having interlined bags across reservations many times on AF without any comment.
What is your experience? Is there a rule written somewhere?
I know that DL is applying a
new rule in January.
