Flights to & from the UK use plastic utensils (I believe any complaints re this need to be dirceted to David Blunkett, btw).

Have used several EK flights beyond DXB to SE Asia and these all use metal utensils, at least in C.

The stupid flaw in this is that in the EK C lounge at DXB (which is post-security) has loads of metal knives & forks on the go, so any prospective terrorist can arm himself with a butter knife & teaspoon in the EK lounge, board a flight to the UK then cause whatever havoc is possible
