Sometimes European carriers like KLM will offer an X voucher on their airline or Y in cash, where Y < X, for VDB. If you volunteer, the voucher will be from AF and will need ot be used on flights that can be booked from their website, presumably including DL codeshares but perhaps not all DL flights or not certain flights booked under a DL flight number. Check the rules.
