First I would like to thank the many members of this board for sharing so much travel knowledge. This is my first post but I have been reading for quite some time.
I had never given much consideration to a RTW trip but now that I am retired and reading FT it is something to think about. I saw there was a spreadsheet that everyone was talking about and tried to download but unfortunately I don't have microsoft excel and cannot access this.

Question: Is it cheaper to plan a business class RTW leaving from a country other than US. I live in the US but there are often inexpensive fares to Europe and would consider starting in Europe. I also have family in Europe so I tend to go visit anyway (family in Italy). I am in NY so a drive to Toronto is not a problem if it is cheaper in Canada. Boils down to ...is it cheaper to plan a RTW from A) US B) Europe or C) Canada?

Thanks in advance and also thank you for many hours of enjoyable reading.
Sincerely,
Pat
