Managed to find a big fat greek fare out of ATH:

https://www.google.com/flights?lite=0#flt=ATH./m/07dfk,HKG,SIN,ICN.2019-04-05.ATHCAI0MS750~CAIBKK0MS960~BKKHKG1MS960*/m/07dfk,HKG,SIN,ICN.ATH.2019-04-11.HKGBKK0MS961~BKKCAI0MS961~CAIATH1MS749;c:CAD;e: 1;sc:b;sd:1;t:f;sp:2.CAD.217919*2.CAD.217894

Nearly all segments, save the short hop between ATH to CAI are in J on MS. I haven't flown MS in J although Flights is showing it's an angled flat product so TIFWIW. This deal is only available on a limited number of dates in 2019.
