I wonder if they will ever get this fixed....
In my experience (BA EC-USA), I simply requested for credit through ba.com. All I needed to provide were the ticket no. and flight details. I didn't send in copies of receipts or BPs. However, it did take BA about 4-6 weeks to post the mileage and TP credits for the missing sectors.
