Hi NZ (Kiwi I gather) ,
First of all let me say welcome to EY, although I'm not an F/O I can assure you that while you're on the A340 only (before you get CCQ on A330 as well) you will love life.
Your average roster will have a JFK, a SYD or a MEL and a LHR. As the A340 does all the ULR's (ultra long range) except Toronto you will be limited to no more that 3 ULR flights per month. That means in all practical terms 14-16 days off and at least 75hrs.
Enjoy every minute because when you get CCQ'ed on the A330 as well things will change.
Still a great airline, great cockpit atmosphere with great guys and galls.
Cheers
