DClinPsy, The UK government has permitted the use of metal cutlery since at least 2006. The Australian government relaxed their rules sometime later allowing all metal except knives and finally, I think in 2010 permitted knives too. I took a QF flight in mid-Jan 2011 HKG-SYD in F and it had the dreaded plastic knife, but the 380 flight I took in February 2011 had all metal. The crew told me that they had use up all of the stock of plastic. Up until 2010 BA flights to SYD via BKK used all metal LHR-BKK and then for the leg down to SYD had to use plastic knives!
