You should be able to update the passenger details from Manage My Booking. If not, you can always amend the situation at check-in.
Thank you for the welcome! There is no option to amend the Avios number in Manage my Booking (only other details). Because I intend to do my check in online (to get the best possible seats), is it still possible for me to amend it at the airport counter after my online check in?
Thank you!
