Going to buy my first RTW.
Start and finish in Moscow, Russia. I need to visit Hong Kong, San Francisco, New York. I would like to be in First class. There is only one flight with First class from Moscow - to London.
So I have some questions

1. How is better to fly - eastbound or westbound?
2. London - New York. BA or AA? And 747 or 777?
3. New York - San Francisco. Direct or with connection? 767-300 or 767-200?
4. San Francisco - Hong Kong. AA or CX? 747 or 777?
5. Hong Kong - London. CX or BA? 747 or 777?

Thanks for help. I am newbie with OW. In the past I used *A.
