Had a good experience yesterday in KIX. Agent escorted me from check-in through the crew only security lines and directly through the concourse to the KIX Airside Lounge. I was then taken by lounge staff to the furthest section that was behind a glass door - a quiet way to get some work in before the wifi-free artic route to CDG.
Security lines were extremely long, so this was a great help in saving some dead time.
I was asked whether i wanted to board first or last - in my case they collected me from the lounge and boarded me first so that I could settle in -it was a full flight. Service great onboard, nice experience overall.
