Motivated by the recent question on blankets, I was wondering which ones among the supplies that one gets on a plane I am allowed to take with me. For instance:
- sleeping mask
- earplugs
- earphones
- cutlery
- ...
I imagine that some of the cheapest items are simply thrown away at the end of the flight if opened, so if that is the case I would not feel bad in taking them away. I suppose that earplugs are a "yes" and metal cutlery is a "no", but I am unsure where to draw the line in the middle. Especially in the case of the fancier items that one may get in business class (or so I am told --- I have never flown in business on a long-distance flight).
