Did you book with AA? If so:
Do you have the ticket number? You can enter the ticket number in here, instead of the PNR:

If you have your credit card statement, the PDF version should show the information as well (may vary by bank).
Yes it was booked with AA. I tried putting the ticket number in as you suggest but that was where I got the new PNR and start from. I've got the original receipt which shows FLG in both directions and funnily enough the BA app missed the FLG return point off but AA didn't originally.
I'll have try and speak to AA on the phone tomorrow I think!
