How is FA Performance Measured/Evaluated?
 

Something I've been somewhat curious about over the years. By and large, I've always had excellent and even exceptional service from the flight attendants. I've always wondered how their performance is measured, given that they generally are working pretty independently and with minimal oversight and supervision.

I have heard from pre-merger DL FAs that if a customer complains about their service, depending on the severity of the case, they may even be temporarily suspended.
