According to the rules, The Great Escapade allows the following stopovers:
OJ travel is permitted only
(a) Within USA/Canada/Caribbean
(b) Within Europe
(c) Within Africa
(d) Within South East Asia/North Asia (*)
(e) Within Australia/New Zealand
(*) North Asia is defined as Hong Kong, Taiwan, China, Japan & Korea
Of course you can start in HNL and end in LAX or start in FRA and end in HAJ but is my understanding correct that the OJ rules do not allow a start in HKG and end in NRT?
