My fiancee and I are trying to do J class from SFO to DPS (Bali). Have plenty of AMEX MR ponits and am willing to purchase economy ticket and upgrade or buy J reward ticket. Problem is, can't seem to find an airline with any availability. Tried DL, CX, and SQ, but nothing besides 390k+ full award ticket on SQ. AC has rewards available, but in mixed Y/J where Y is for the long-haul SFO to Asia.

Any other tricks? Running out of ideas, but of course obsessively checking for availability. Would be willing to do J from SFO to Asia, Y to Bali, on separate tickets.
