I have made a booking with Lufthansa and initially listed my Miles & More account for credit of eventual miles gained. However now I want to credit the miles that will be gained from the flight to another mileage program (compatible with LH).
I can access my booking online via the Lufthansa website/My bookings. I was able to add the other mileage program to the "Passenger" item of my booking but now it shows both the Miles & More and the other program (with my numbers) and I have no idea which one will be used to credit my miles to.
How can I choose which loyalty program to credit the miles to?
