I can tell you the crew on MU578 def smoked the whole flight from LAX-PVG I will only hope the return will be No smoking. If the food was improved I can't imagine what it once was. I was beyond disgusted by everything they served outside of the fruit and Hagen Daz. Now PVG-BKK on FM was smoke free and had great service but they still serves sour swill for their meals.
