Amy Winehouse's dad, Mitch Winehouse, was spotted at JFK this afternoon ... just hours after his daughter's death. 

Mitch was reportedly in the first class lounge, pacing up and down as he talked on his cell phone.

He was scheduled to perform at the Blue Note in New York City, but canceled the performance.
