Cathay Pacific Asia Miles - HKG to INDIA using Miles

I've searched and searched and can never find open seats to DEL, BOM and BLR. I wanted F seats nothing, tried J seats again nothing. I've looked at dates from May thru December - anyone have tips or strategies? Thanks

SFO was the same until after the new flight was added, and not until the new flights actually started. So there can be more availability by then.

Also upgrades are much easier to get than simply F/J full redemption awards. If you have Asia Miles, you can consider that.
