Basically on ITA you can do a round trip in first and bus. around the world with 40K miles. I have got it to price with six stops in both directions, hkg,akl,nrt,zrh,cdg, and a host of others. airlines used is all over the span to include F/C on SQ 777 and bis on the 380, BA first, CX first. I could not do a sole skyteam. Yet...
