I am looking for suggestions for the first part of a DONE5. I am looking to credit to AY+ but the tracking year ends part way through the ticket. At this point I will have needed to get from OSL to EZE and looking at options to collect at least 37500 tier points (happy to buy remaining 7500 with Avios). Travel will be in 2nd week November 26 and ideally will not require too much additional travel time. Would also be good to avoid using more segments in EMEA than is necessary to allow extra holiday at end of ticket when returning to OSL.
The alternative is to give up on getting AY+ Gold at the start of the ticket (or do additional points run prior to RTW) and maximise use of segments in second part of trip (to be taken in 27). If I did this I would likely start with OSL-HEL-DWR-EZE using AA codeshare where possible

Edit: in some way related to this. Is the restriction on OSL-DOH as first leg a limitation of the Oneworld tool or a RTW restriction?
