The website tells me that I have 2 "ISUC - INTL SEGMENT UPGRADE CERTIFICATES" available that expire in November. No idea how I earned these, but I am the lowest Elite. Question 1: Can I give these to my father and stepmother? Question 2: Can they use them on a STL-HNL leg (one way only)? If the answer if no, might they try and ask the gate agent about it and hope for a favor? But since they're electronic, I don't know what they could show for proof...

Thanks for any advice!
