I was under the impression that when redeeming miles, one can add a stopover for free (at least if not terribly out of the way). It didn't work for IND-SFO-SEA-IND. I was expecting to get it at 25k miles but it came up at 35k. If the free stopover worked, it should have not picked up the SFO-SEA segment of 10k, no? I did select saver award for all 3 segments.
Any idea why no free stopover here?
