Need advice from those in the know. I need to travel from Europe (but can leave from N Africa if a lot cheaper) to GCC (Doha, Abu Dhabi, Kuwait, Bahrein), Australia (Melbourne, Adelaide, Sydney), USA (NYC) and Europe (London, Stockholm, Helsinki, Berlin, Munich, Paris)...

I think a Oneworld RTW Explorer ticket is best given the destinations. Has anyone done a comparison where buying this in Business or (God forbid) Economy makes sense?

Responses appreciated. I will happily provide free advice on France - am recognized by Condé Nast and Travel and Leisure as specialist and can do a deal.

Merci, Thanks, Danke in advance for any concrete advice!!!
