I just read a post somewhere here, sorry folks can't for the life me find it now ~ and I believe it was locked, but it dealt with the scenario of a PAX in F who was ill and continuously vomiting for hours on a transatlantic FLT. This poor sick person was asked by the FA to move back into Y which had a very light load. (The OP of that thread was asking about her rights etc. and compensation ~ some lively discussion ensued LOL).

Anyway, the description of events (on that thread) is a very good illustration of the differences of what the duties of stewardesses of yester-year were, and what those of today's FA, seemingly, are.

First of all, we would have first paged a doctor, and regardless of that availability, the 70:s, stewardesses, in rotation, would have sat watch over such an ill person up until landing. The captain would be fully briefed and updated. In the description of this recent event, seemingly, today's FA merely asked the PAX to move, so as to not disturb other PAX in F.

(While vomiting is fairly common around take-off and landing, continous vomiting would indicate a more serious situation ~ even if alcohol induced).
