No F on the 744 or 333 flights. From what I could see, when the 388 is operating, its only J service as the highest offering - unless I’ve missed something. In any case, with the overnight flight in J, expect a meal service after departure then breakfast about 2 hr to 90 min before arrival. There may be a drinks service first if you’re lucky, otherwise the crew may “integrate” it with the meal (which is a lazy way to do it). Hot towel(s) sometimes. The crew will be happy to allow pax to maximise their rest (sigh). Oh, and there should be PJs and some sort of rolled up bedding in addition to pillow and blanket. Should also be able to pre-order meal.
