Thanks very much for your help.
It would depend on what the voucher says. For example, if it says that CO must be the governing carrier, then all flights must have CO flight numbers.
If it says valid on CO/CoEX only... then not only must it have a Co/CoEx flight number, but all flights must be operated by one/both of those.
