Just piggy backing on this thread - have realised my partner (CX Silver/OWR) can hit BA Silver (OWS) on our upcoming flights to SYD. Her CX FF is on the booking currently along with my BAEC Silver FF, but I want to change hers one to her BAEC FF to get the TPs.
We've already reserved seats on CX for free, so would we lose these if her FF changed to a lowly BA Blue?
