My recollection is that there was a restriction that within the continent of origin regarding stopovers, originally it allowed two, only one per direction, later relaxed to only allowing two, regardless of direction. In the version I just accessed via EF, there is no restriction on stopovers in the continent of origin, although the rule wording is a bit confusing:

STOPOVERS: 2 STOPOVERS REQUIRED AND UNLIMITED FREE STOPOVERS
PERMITTED ON THE PRICING UNIT
UNLIMITED IN SOUTHWEST PACIFIC
2 IN AREA 3
UNLIMITED AT ANY POINT.

I'm not clear what "2 in area 3" means. Is area 3 the same as TC3, meaning Asia/South West Pacific? Surely one is permitted more than two stopovers within Asia and South West Pacific? I routinely have three stopovers in Australia and one or two in Asia.
