I’m hoping to get some info here bc LH has been absolutely no help. I am flying Atl-Fra with a 3 year old.
LH advertises the following "Child fare: Children aged between 2 and 11 years (up to their 12th birthday) must occupy their own seat and travel for 75 per cent of the regular price of the flight on most routes and on almost all fares. Please note that babies who turn 2 years old during the flight will be required to occupy their own seat and will be charged the child fare."

When I booked (before I found this info) I was charged 2 adult fares for me and the kid. Now I saw that in the confirmation my child's ticket is even MORE expensive than my adult ticket. Can anybody explain this to me? When I called LH, they told me that they don’t have any child fares available in their system at all going to FRA this entire year. Somehow I feel like something in their system is going wrong with all this. Is this some false advertisement? What does one have to do to get a child fare?
Thanks in advance for any insight

PS: Yes, when booking I accurately put in my child's age as 3
