I was actually looking at a slightly different configuration. See below. I am working on a trip…..LA to Shanghai to Hanoi to Dubai and back to LA. This for me, wife and kid over Christmas break. The dates and flights are challenging but doable. The LA to Shanghai would be on China Eastern which I have no experience with. I did fly First on China Air to Taipei on an old 747. We finished the champagne in First and went to work on the biz class select. Needed to clam nerves after shaky takeoff and to wash down the fungus in coconut milk for breakfast.
