Sorry for the long title to the string but I wanted to precisely describe my circumstance and perhaps someone can clarify for me. These are my assumptions, pleas correct if I am wrong. So long as I and my spouse / partner are traveling on the same PNR, then we are in the UDU queue together at my priority whatever that is based on class of service yada, yada, yada. So then, WHY did the CO system keep spitting the PNR and upgrading me and not my wife????
