It’s unannounced and no one knows about it until it happens. 

Occasionally, they’ll pick up multiple Medallion members from one flight and shuttle them to their gates as a surprise to say thank you for flying with Delta.

The Delta Porsche transfer, or “Unicorns” as many frequent flyers call it has been see in ATL, DTW, JFK, LAX, LGA, MSP, SLC, SEA and SFO
