Personally doing this routing twice on 16 segments, just altering the starting point and ME destination:
WAW/MXP-XLHR-MCT/AUD-LHR-LAX-MIA-ORD-JFK-HKG-NRT-BKK-BOM-XHKG-AKL-SYD-XLHR-WAW/MXP
The last of my 20 segments (allowed on paper ticket, gone a couple of years ago) AONE4 was:
ARN-XLHR-MCT-LHR-LAX-XJFK-XDFW-ANC-DFW-JFK-XHKG-NRT-HKG-BKK-SIN-XHKG-AKL-SYD-BKK-XLHR-ARN
which is basically the same, but as HKG-BOM at that time was C/Y only, and I wanted to maximize F travel, the Asia trips are shortish.
