All of your items were what came to mind for me. I suspect that, in the event of an unscheduled off airport landing (pretty words for a crash), there would be emergency supplies available, or her personal stuff would be lost onboard anyway (I don't think that she could carry her "kit" while actually working while inflight). What she needs is something to get her to and from a hotel, and while in her room, and that she can actually carry onboard. Sewing kit and FAK come to my mind first...
