Hi, this is my first RTW. I'm looking to get max miles and BA TP out of the journey. I am currently BA Silver

The only places that I must go to are underlined.

ARN (BA) - LHR (BA) - SFO (AA) - DFW (AA) - GUA (surface) - PTY (AA) - MIA (QF) - LAX (QF) - AKL (QF) - SYD (surface) - DRW (QF) - PER (QF) - CGK (JL) - NRT (JL)- KUL (CX) - HKG (CX) - BKK (BA) - LHR (BA) - ARN

Would anyone be able to
1) Validate the itin
2) Propose changes to maximise mileage / TP
3) Give any advice on how to get this ticketed out of Sweden. I have a friend there who I could get to do some work for me if required.

Thanks.
