I've got an upcoming flight CLE-MBJ... My family will be traveling with a friend's family. I was able to upgrade everyone from Y to F using RPUs, but I was one short so my friend himself is in steerage. He is on a different PNR, how do I go about adding him to the Upgrade standby list for a complimentary upgrade? Is this still done Day of departure at the airport like in the CO days? Or is there some super-secret GS benefit I can leverage here to get him moved up front?
