Hi Team
I'm struggling to get Avios credited (if I can) for a Fijian flight I took in July, approx 1 month after BA and Fiji started doing a code share for flights to/from Nadi.
The drop down menu at BA.com doesn't show Fijiian in the list of OneWorld partners who you can file a claim for...

I booked this direct with Fijiian on the same day the alliance was announced purely by coincidence on 6th June but couldn't add my BA Number to the Fiji booking.

Am I chasing a lost cause here, or is there any other tricks to try?
Thanks, RP
