If you are not PPS, if you are star gold, this also helps. or KF Elite.
A good travel agent can also help you. Depending on skill they can waitlist, monitor and clear you.
If the flight is full, the flight is full. Nothing of above will help you in such a case. I ended up plenty of times in Y cause the waitlist never cleared, but i had to fly. ICN, BLR, BOM are such destinations.
