Yes you are right about two apparent J lounges at DOH but I don't think that's dysfunctional, more gaming the system. I presume you mean you were flying Y but with status because I went to the Al Mourjan lounge on a CX J ticket. The OneWorld status lounge is a better option if you like to serve your self rather than be fussed over.

Of course in a parallel universe there is probably a Qatari making exactly the same argument about Galleries First and the Concorde Room at T5.

As for the award system not working, I don't have a clue why they cannot be booked online.
