For an FO on the A330 it is very busy at the moment as so many FOs left recently; you could expect to fly around 90 hours a month. As for captains it is getting busier due to the FO shortage - they are flying captains with captains.
The A330 has the greatest number of destinations of any fleet here:
Middle East, Africa, Asia, Far East and Europe. Most flights will be layovers. Generally 24 hour layovers with some up to 48 hours.
As I previously mentioned on this page, you will be allocated some of your days off down-route. You don't get any choice in the matter.
