[quote]As SLF I've often wondered at what point the cabin crew are told to buckle up too. There's no point them unnecessarily risking their necks for the sake of some passenger's G&T.

The cabin crew are kept in the know via the pilots getting advice from planes flying ahead nor indeed from their own weather radar.
This of course is passed on to the crew if they have not already been briefed before takeoff.
Of course unexpected happens and it's not always air turbulence.
I really don't know what was going on with the news and these flights. Nobody is typically served in early climb or descent. Sometimes we can't even get a drink (PDB) on the ground
