italdesign if you look at
https://www.qatarairways.com/en-dk/l...l-mourjan.html and
https://www.qatarairways.com/en-dk/lounges.html you can see "Access is for Qatar Airways and oneworld First Class and Business Class passengers only.". That means No guests or OW status passengers allowed.
I have requested the moderators move this to the
http://www.flyertalk.com/forum/qatar...ss-lounge.html where there is much more information available.
