I expect that I will be purchasing a Star Round-the-World fare this fall. I can combine a meeting in Europe with one in Asia.

I have studied Dorian's charts on fares and rules and I am omly left with a couple of questions:

1. Do these fares fluctuate very much?

2. Does one just phone AC reservations and book over the phone?

3. Dorians chart shows an RWLite, but for economy only. Would there be a business fare also?

4. I have calculated my mileage needed from a Great Circle chart. Would this be much different if done when booking? [I would be 19,964 miles without any add-ons]

5. Any other tips from people who have used these fares?

Many Thanks
