Person A drives and parks car at T5 and departs on flight 1.
Then 48 hours later person B arrives on flight 2 and wants to pickup said car and drive away in it.
In those 48 hours person A and person B never meet, so no way to pass along key and parking ticket.
Anyway to do this?

Vallet parking can handle the key that would be required for the "handover" but they would need a ticket to claim the car, and since A and B never meet there isn't a good way to pass the ticket along.

Any suggestions on how to make this work?
