Thank you, where did you pull this up from? Can I use a website like ITA Matrix to pull all the rules?

Also is there information on how the pricing works for RTW? Is it a combination of

`Base Fare × Starting city multiplier × miles flown × stopovers + taxes`?

Or specific airlines / routes cost more than others for example, is NRT->ZRH with Swiss is more expensive than ICN->MUC with Lufthansa? Is it affected because some airlines have price their tickets with low fare but very high fuel surcharges?
