I've searched the thread and have not seen a definitive answer to this question.

I have a 6 hour layover at LAX before taking the LAX-DOH flight in business. I know QR operates out of Terminal 2, but was wondering if anyone has attempted to use the TBIT OW lounge?

According to the OW lounge access rules it should be allowed, but there were some comments on earlier threads that said they didn't think it actually would be.
