Okay, guys. Big confession. Upon reviewing my notes, I realize I have made a mistake... It wasn't really as impressive.
9:20p Wheels touched ground on Runway 7L
9:26p Doors opened at Gate 20
~9:35p Priority-bags came out
~9:37p Out customs door
So, it was actually 17 minutes, not 12. But still, bags were delivered around 8-9 minutes after parking at the gate.
