Hi Mayflower,
If he's got time on the A330, I'm sure there is work in europe for him. The problem is licence, I'm sure he knows himself that he would have to convert to a european licence and that's not as easy as it sounds. The advantage he has is that he has time on the A330. My advise would be to start the licence transfer process (ie exams etc) and go from there. As far as working in the EU and visas etc, I'm really not up to date with that.
Good luck with it though.
