Oh good. That means we can eat our Saturday night curry in the Ops building with proper implements again instead of having to use our fingers! (The rules applied just the same to those of us who live & work airside as well as the pax.)
I believe the 'official' reason is that everyone has strengthened cockpit doors now but there's a rumour that everyone's fed up with the fact that the American airlines hadn't followed the guidelines. This gave them an unfair competitive advantage compared with those that had taken all their nice cutlery away.
'course won't make any difference to me 'cos the seats I can afford still dole out plastic knives and forks...
