I am a Sapphire member (BA silver) and I have booked a reward trip in July on CX through BA website with Avios in business class. The route is SIN-HKG-TPE. I have added my BA number in the booking.
I am flying QR in C class to SIN from OSL in June and will become BA gold (Emerald) when I reach SIN. My question is: Do I need to do anything to update the CX reward booking so it reflects my new Emerald status? Since I booked as a Sapphire and I will then have an Emerald status before the flight. The crew will also see the Emerald status?
