How do I add a Qatar flight already flown so I can get tier points? I flew LAX-DIA in J cash purchase, so would rather not miss on tier points.
Sorry if the question a bit naïve, trying to find an option on ba.com but can't see it. There is an option to Add Booking but it does not recognise Qatar reference. This was originally booked via TA as Y, but then I asked for cash upgrade at Qatar check-in at LAX.
