I think we're conflating two things here - please correct me if I'm wrong:

- A diamond member can 'forcibly' open up standard award availability for themselves and their companions, as long as they're on the same flight.
- A diamond member cannot open up standard award availability if they're *not* on the same flight as the people they're redeeming for, but the waitlist request will open up by the requester's (diamond) priority.
