Can I ask a follow-up question on this topic? I am looking to book my sister (who is a silver medallion) an award ticket and myself a regular paid ticket to the same destination (flights and times). Is there any way I can link her ticket (PNR) to mine so that she is eligible for a better shot at getting upgraded? I am 99.9% sure the answer is no, but I thought I would at least put the question out there. Thanks!
