Hi Mwenenzi, thanks for your help. There are no errors when I enter (I have surface travel from Amsterdam to London and Sao Paolo to Rio. Also the first stop in London is a stopover for Moscow.) Not sure if this means I'm good since I haven't booked yet but the engine will price (both economy and business). Thanks for the advice on AA. I did indeed select them on the first leg to SYD with OW and it dropped me by $200. Are you recommending that I book AA direct and start my RTW from Sydney?
