Cabin secured for take off / landing - no, use of mobile phones at critical phases of flight stopped - no. Welcome on board - same feeling as stepping on a London Bus with as much interaction!!!!
I have every confidence Flight crew would get me to my destination safely. Less confidence if a situation arose the cabin crew would be able to deal with it efficiently and safely so longer journeys with other Gulf carriers, local journeys Loco.
There are demographic factors in the market GF is serving that account for difficulties and yet these should not be allowed to overide proscribed procedures / requirements.
Just my 2 cents worth..
