Not strictly on topic, but I just noticed that JAL seem to be offering Perrier-Jouët Belle Époque on some routes in F (including one of my upcoming flights). So, my view is that as long as the FAs keep the PJ flowing (and as long I as am possessed of the power of speech, or even just the ability to point and grunt, it should continue to flow...), I really won't care how awful or just plain inattentive (which, in any event, I struggle to believe is possible with JAL FAs) the service might be!
