GROUP: Lost & Found Property @ Heathrow Airport

AUTHOR: Aviva Miller

We lost a very sentimental hand-knit bag and would be so grateful to anyone who could help.
We flew on Wednesday, April 15th, into Heathrow (terminal 3) and transferred to our flight to Larnaca (terminal 5).
We flew British Airways. First leg was American Airlines operated by BA.
As of now, Lost and Found and security tell us the bag was not found.
