According to. http://www.wandr.me/RTW_Fares.aspx/ByProduct/LONE6
Fare from Cyprus is only $2513.
However when I try and book it online, I can only book alight to amman and then it seems impossible to book flights to say, London or USA.it doesn't find any availability from LCA to LHR although I can see flights on ba.com. The error says can only cross atlantic once. Am I doing something wrong?

Seychelles seems even cheaper - is that not bookable either?
Thanks
Jo
