Flew Qatar J for the first time last week. First leg DUB -DOH on the 7878 (1-2-1) and DOH - NRT on the A350k Qsuites. Have to say it was a very good experience. Staff very friendly and mostly great service. The first leg was exceptional, flexible, quick and always ahead of what you wanted. The second leg had a few hiccups (forgotten orders, not as friendly across entire staff and no flexibility - sitting in the 2 middle seats we often wanted to bother order with the left side as the right was slower but that was never accepted). Overall we were exceptionally happy as some of the hiccups might have been down to half the flight duration being quite bumpy.
