Flight Attendant or Cabin Crew???
I'm not worried what country thought of the name, so what if it is American or British or whatever.
This is more to do with what the name implies, cabin crew is restricted to the cabin? I hope not and i hope the newer less experienced crew don't think that. Pilots, Engineers are not names that suggest in anyway that they are only in the cockpit.
I think Flight Attendant is more appropriate as is Cabin Crew provided the person being called that realises that his/her job encompasses the cockpit.
Sweet FA.......out
