2 here::
1) LAX-oLIM-EZE//GRU-xLIM-oLAX-oSFO-LAX (LA, AA)
- 115K Asiamiles in J each (had 2 tickets), when a straight LAX-oLIM-EZE//GRU-xLIM-LAX would have cost 120K, and there was a small chance that I would be able to use the 'dump' LAX-SFO-vv sectors at a later date.
- you CAN go through the origin city (LAX) and continue with the award ticket. Although I ended up cancelling the above award, I used this as a reference when ticketing pushed back for the next ticket (#2)

2) SFO-xHKG-oDEL-xKUL-oSIN-xHKG-SFO//SJU-xDFW-SFO (CX, MH, AA)
- 160K Asiamiles in J each (2 tickets for Sis/nephew visiting folks in India and me in SIN), when a straight SFO-India/SIN/OpenJaw would have been 145K Asiamiles. However, a) they got a lie-flat for India-SIN (rather than ponying up ~USD550 or 300ish each in biz or coach, if that segment had been a revenue ticket), and, there was a decent chance of break to Puerto Rico later in the year.
- you CAN use a stopover as a transit
