I know this has probably been asked a hundred times above, but quick check if somebody would be so kind, I’m pricing up an Asia itinerary for my parents with Propeller travel, but didn’t realise I had to be on the PNR in order to use a GUF2 for them. If I manage to get BA to price up the same itinerary, can I use a joker via BA even if I am not on the PNR?

Thanks, Pilot37
