On topic, I do see the OP's point, up to a point - but how long a flight would be operated by such a plane? Surely just wipe your hands with the sanitiser kindly offered by the CC and get over it?
I've nothing to get over. I'll say again that I had every faith in the cabin crew's efforts to maintain good hygiene. The concerns I outlined were those expressed to me by them. I was on the plane for less than an hour but remember the length of time they and the flight crew have to spend on the aircraft in the course of one shift is probably the same as a holiday flight to the Canaries or even longer.
