1. It is 100% on you as the pax to make certain that the KTN is properly entered in each PNR. But, in this case, the poster has said twice that he has done this, so not sure what your post is meant to suggest.
2. I agree with others. If OP has a KTN and it is properly entered in each PNR and he is at 50%, there is something wrong and he is on some list. He may need to go through the redress process.
