Got my first ride today coming from PDX, connecting through SEA to AMS. They had two cars, one Macan and one Panamera 4S waiting for 3 of us getting on the AMS flight. They were boarding as we landed. I cleared for an upgrade to D1 using a GUC
on a B fare, I was 2 for 2 for the upgrade but it turned out to be 2 out of 4 after we boarded. Nice treat indeed.
