I have a couple of similar questions as the OP, however slightly different.

The VDB voucher says "ticket by: 18DEC04", can I ticket by that date for later travel or does travel need to be complete by that date?

Can I do an open jaw? There is no specific restriction on the voucher, other than it states round trip. Profile code is: PMO, Profile name is: DBC Free, Treat as type B voucher.
