Retrieve your booking by logging into your account on lufthansa.com or miles-and-more.com. Click "Add or change your frequent flyer card" option, select a programme from the drop-down menu and enter the appropriate number.
There's a warning message "If you are a status customer please note that editing the frequent flyer card number might cause a seat reservation change."
