One of the things I read was that the daughter would only eat hot food. She said she had no way to heat food on the plane.
Do they not have cup-o-soup where she comes from? If I had a kid who had that requirement I'd have at least one of those tucked away, maybe two. They always have hot water for tea.
In fact...maybe I should bring that on my next non-VX transcon. If I'm not special needs would they give me enough hot water for instant noodles?
