AONE4 Itinerary - Pls. Help.
 

Appreciate if all of you experts to comment on the below itinerary

BKK-SYD-PER-DRW-ADL-xSYD-SCL-IPC-xSCL-EZE-xSCL-FRA-xLON-KEF-LON-HKG-ICN-xHKG-SIN-BKK

I want to max. the number of stopovers and the number of segments in each of the 4 continents. All suggestions are welcomed. Thanks in advance!

LGW-KEF-LGW can be purchased separately for around GBP39 each way (coach, but hardly a come-down from BA's intra-Europe biz), freeing two segments for something a bit more ambitious. (Note also that KEF has been seasonal for BA.) Depending on your desires, LHR-CAI or LHR-ATH lead you to interesting destinations, and CAI still enjoys 3-class service afaik.

Thanks! You are right ... ATH or CAI is a better place to visit (I have not been to either).

Is there any limitation as to the max. number of stopover per city and max. number of transfer per city?? ... I don't seem to find the answer to this in the sticky.

The only limitations are:
- Only two stopovers in the continent of origin (your itinerary as posted fails this - it has 3).
- You may pass through your city of origin, but you cannot make any more international trips after returning there (hence this is only useful in countries with domestic OW flights).
- Maximum 20 flight segments in total and 4 in each continent except N America which allows 6.
- Otherwise no restrictions.
