Thanks for the replies all. As far as (scheduled) overnight stops are concerned I’m pretty sure this airline has none. It’s a small fleet of 10 x A3xx with one hub, flying short haul routes and
AFAIK all aircraft are back to base every night. I take the point about a change of uniform and provisions for unscheduled stopovers. I don’t think putting them in the hold would help since they seemed to access them during the flight. Anyway, it’s something that has cropped up before (for me) and struck me as a bit of an anomaly. Sometimes they put them in the biz class coat lockers. It’s just a bit frustrating when you’re sitting there with your legs trussed up around the bag under the seat in front of you and you see cabin crew go to get a scarf out of their carry on in the overhead bins.
