Just a remark, after reading this thread and the RTW proposal involved.

Critics have mentionned time money and time concerns. I think they missed a key element. Some FTers, and given the threads w/r/t FTW flights, I guess it's a not insignificant number, wouldn't consider such a long itinerary in coach. There would be people torn between not attending and submitting themselve to the harrowing experience called Y, because J cabin would sell much quicker.
