For the last few years, I've used my Lufthansa ID (e-mail address + password) to maintain a profile with Lufthansa that could save my personal information including Aeroplan FF number. After completing a recent booking, the LH website prompted me to convert my Lufthansa ID into a Travel ID that could be used across the LH Group websites. I did so, and most of the information seemed to carry over successfully, except the frequent flyer number. So I tried to add it manually and receive this error:
Trying to add a non-M&M FF number during the booking process also does not appear possible anymore:
Why is Lufthansa making "improvements" to its website that reduce its functionality? Do they want more people to "contact the Service Center" and increase their operating costs?
