I was just watching that BA Documentary the other day (https://en.m.wikipedia.org/wiki/A_Very_British_Airline) and the scene on premium cabin cabin crew training - where they told trainee cabin crew that the cost of a full fare ticket LHR-LAX was c.£10,000. There was then a comment from a new trainee that that fare was a substantial portion of their salary - and they would never have flown in premium cabins.

Now that got me thinking (dont get me wrong I know crew are trained to be professional), but would there be any jealously or resentment if you were a CC serving the F / J cabin (esp amongst mixed fleet where wages are lower?). If it were me, I would probably be thinking - here I am earning what maybe £20k+ in a good year, and you have got these schmucks spending half that on a ticket?
