No, no, -- you're right. I was talking about my own QR experience.

For example, I just flew CDG-DOH in F on a miles redemption, arriving DOH close to midnight. Then I flew the next morning DOH-BOS in paid J on a separate ticket. Checking in at CDG, I asked if they would check my bag through to BOS even though it was on separate tickets. The agent's initial response was she did not think that they could not do that. I asked if she could check, please. Supervisor came over and looked at the records on the screen. I understand little French, especially when spoken at high speed, but I distinctly heard the supervisor say, "Il est PLATEENOOM, c'est bon." Bag checked through with a smile.
