Trying to save myself a phone call to BA. I made a reservation before the switch to Avios for a booking SFO-HKG-BKK on CX in Business Class. Silly me, don't know what I was thinking as knowing myself I should have realised I am too addicted to First to want to fly anywhere else. Anyway I would like to upgrade the redemption to First Class. I am assuming this would be at current redemption rates rather than pre-Avios rates. Has anyone encountered this situation and if so what is the answer? Many thanks.
