1000% True and yes you will handle all other airlines, not Qatar Airways because Qatar Airways Passengers, Tickets, Boarding Passes, etc are handled by QR Staff mean (Qatar Airways Main Department Earning Company Uniform) You will be in QAS Department and you will not wear QR Purple/Red color uniform because that is only for CSA Hub or CSA QR Department…

You are going to join QAS (Qatar Aviation Services) department and it’s not the main department and you will wear Green Uniform.
