Thanks for all your help and advise, I took it all on board.

I called AA today and booked ARN-LHR-DXB-LHR-SYD-PER-HKG-DPS-NRT-CGK-NRT-JFK-LAX-ORD-LAX-LHR-ARN

I know I could have routed differently for more miles etc, however timings didn't work out and I don't have the flexibility now to do things different. The main reason for including SYD is to try out the A380, although available to SYD it was not available for SIN anyday during the week I could leave. I also wanted to fly back from NRT to use an EVIP which will also get me to LAX as the flight leaves on the same day.

Unfortunately timing did not allow for a devation to SJU.

I have booked this now and am waiting for fares to come back with the price. It was suprisingly easy to do with AA, took just over 20 minutes on the phone.

Can they fare this is € or £ even though it is starting in ARN.
