SAN FRANCISCO (KPIX 5) – A San Francisco woman is thanking a United Airlines pilot for returning some small but precious cargo.

Brit Morin thought she had lost her engagement ring for good, but it was returned to her with a handwritten note from the person who delivered it to her.

A United gate agent found the diamond ring, put it in a safe, and then gave it to a pilot who brought it back to her in San Francisco.

United responded, saying “This is great to see our employees being recognized for their care for our customers.”
