I have a similar but opposite question.

My wife and I are booked on separate PNRs for our vacation to CUN. I am GM on award ticket, she is kettle on paid M ticket. After booking I called and had the PNRs linked so she can sit next to me in the exit row.

1. Her itinerary does not show anything about an upgrade, but mine says "upgrade requested". Would I clear at the GM window by myself, after all FOs clear, or would I not be on the list at all?

2. In case of IROP, does being on linked PNRs keep us together?

3. (OT) As a GM on DL flights to/from CUN, do we have access to the Aeromexico lounge since this is an international flight, or would we have to be flying on Aeromexico?

Thanks for any answers!
