If a passenger off-loads (or otherwise chooses not to travel) their bag must be off-loaded (or not loaded in the first place) - basic security.
If a passenger chooses not to travel there is no refund - passenger agreed terms and conditions as part of the low fare deal.
If a second passenger wishes to add and pay for a bag to their existing flight booking - they can.
All baggage must be clearly identified with an on-board passenger - same for all airlines.
