I am not sure what is the rules for the manager to greet MPC members on Board. My experience is around 1 in 5 flight, someone will come and welcome me and hand me a bottle of water. The best time was they offer me to have "Priority Meal" , eating meal ahead of other Y..well, I won't want to do that, looks odd!.... anyway, i usually give up the dinner from LAX, just wrong timing...

Just curious...
